Tattoo Needle Cartridges Bulk - Tattoo Needle Cartridges Bulk

Why Buy Tattoo Needle Cartridges in Bulk?

Professional shops burn through cartridge needles. A busy artist can go through multiple boxes per week across configurations. Buying in bulk ensures you never run out of critical configs mid-session or during a booked-out week, and consolidating orders reduces the number of shipments and the shipping costs that come with them.

Eikon's Buy More Save More program makes bulk buying practical: 10% off when you pick up 5 or more boxes of Eikon cartridges, mix and match across any combination of configurations or sizes. No promo codes needed, add the quantity to the cart, and savings apply automatically. The same program applies to shading needles like Hydra Needles and Griffin Tubes, so shops can stock across product lines in a single order.

Every cartridge is individually sealed in its own blister pack within the box. Sterility is maintained regardless of how many boxes you order, and artists pull fresh, sealed cartridges one at a time as needed. The same cartridge you open from a 5-box order is identical to the one from a single box.

Orders over $150 CAD ship free across Canada (ground), and same-day shipping is available on orders placed before 1:00 PM EST, Monday through Friday. Eikon ships from Kingston, ON, with no cross-border duties or customs delays for Canadian buyers.

Complete Range of Cartridge Configurations in Bulk

Round liner tattoo needle cartridges in the full RL, SRL, and HRL progression for every type of linework. Standard Round Liners (RL) from 1RL through 14RL for the crispest lines, Straight Round Liners (SRL) for bolder lines with more ink per pass, and Hollow Round Liners (HRL) for bold lines with less skin trauma. All Eikon liners include the stabilisation system for straight needle travel. Available in all three Eikon diameters (0.25mm Purple, 0.30mm Blue, 0.35mm Red for RL; 0.35mm Red for SRL and HRL).

Curved magnums (soft edge) for large-area shading, colour packing, and blending around body contours, Eikon's largest configuration category with 20 options across all three diameters and both taper lengths (long and medium). Standard magnums (flat edge) for working against lines, into corners, and for geometric shading where defined edges matter, 6 configurations in 0.35mm Red.

Round shaders for precision shading in smaller areas, 5 configurations in 0.30mm Blue. The looser grouping deposits more ink per pass than a liner of the same count, making round shaders the right tool for detail shading, gradual transitions, and tight spots where a magnum would be too wide.

Beyond Eikon's own line, the store carries Kwadron (50+ configurations, three diameters, two tapers), Cheyenne Safety (Standard and Premium lines), TEX (37 artist-selected configurations), and Lotus (full lineup across bars and cartridges — 60+ configurations including Medium Taper Liners and 0.20mm Ultra Small Liners; exclusive to Eikon in Canada). Mixing brands within a bulk needle bundle lets artists stock their preferred brand for each configuration type, liners from one, mags from another. 

Needle Diameters and Tapers: Building Your Bulk Inventory

Bugpin (0.25mm, Purple label) is Eikon's top-selling liner diameter; artists use it for fine-line work and micro-realism, but also as their everyday liner because they prefer the finer puncture and tighter groupings. When stocking bulk liners, Purple boxes are where most shops start. The 0.25mm is also available in curved magnums for artists who want smoother tonal transitions in their shading.

Standard diameter (0.35mm, Red label) creates a bolder puncture with more ink delivered per pass, the go-to for traditional-style linework, colour packing, and any application where maximum ink deposit matters. The 0.30mm Blue sits between the two: fine enough for detailed work but with slightly more ink per pass than bugpin. For a complete inventory, stock all three diameters in your most-used liner counts.

Long taper is the default across 90% of Eikon's lineup; the sharper point creates smaller puncture holes with less resistance per strike, making it the standard for both lining and shading. Medium taper appears in select Red Label curved magnums for colour packing; the blunter tip holds more ink at the point of contact and deposits more pigment per pass, which can mean fewer passes and less total trauma for saturation work.

Needle count and diameter interact to determine line weight; a 5RL in 0.25mm produces a finer line than a 3RL in 0.35mm. Stocking multiple diameters in your core liner counts (3RL, 5RL, 7RL) gives artists flexibility to adjust line weight without changing needle count. Eikon's colour coding (Purple, Blue, Red) makes it practical to organise and identify diameters across a large inventory.

Cartridges vs. Traditional Needles: The Bulk Perspective

Cartridges simplify bulk inventory: one SKU replaces separate needles, tubes, grips, and tips. Each cartridge comes factory-matched; the tip, housing, and needle configuration are a single disposable unit, so there is no tube matching required. For shops managing inventory, this means fewer product lines to track and simpler reordering.

The biggest practical advantage of disposable tattoo needle cartridges for a busy shop is speed of setup changes; an artist can go from lining to shading with a cartridge swap that takes seconds, versus breaking down and rebuilding a traditional setup with a different needle and tube. When artists are working across multiple configurations in a single session, those seconds add up.

Traditional needle-and-tube setups, whether with reusable stainless steel tubes or disposable tubes, offer customisation that cartridges do not. Artists can custom-solder configurations, tune machines for a specific feel, and work with the power profile of coil machines. Both cartridges and pre-made bar needles deliver consistent, factory-manufactured quality.

Pricing between cartridges and traditional needles is now comparable. Eikon carries both: Eikon Cartridges, Kwadron, Cheyenne, TEX, and Lotus cartridges alongside Hydra pre-made bar needles and Griffin Tubes for traditional setups. The Buy More Save More program applies to Eikon Cartridges, Hydra Needles, and Griffin Tubes; mix and match across product lines. 

What Cartridge Needles Do Professional Tattoo Artists Stock?

Most professionals build their core inventory around three to five liner configurations and two to three magnum sizes. The exact configs depend on the artist's style, but a common starting point: 3RL and 5RL in 0.25mm Purple for fine and detail work, 7RL in 0.30mm Blue or 0.35mm Red for standard outlines, and 9SEM or 11SEM curved magnums in long taper for shading and colour packing.

Bugpin (0.25mm) liners are where most shops see the highest volume; this is Eikon's top-selling liner diameter. Standard diameter (0.35mm) liners stock behind it for traditional and bold work. Stocking both diameters in your core liner counts rather than loading up on one gives artists at the shop flexibility across styles.

Artists who work with SRL or HRL stock those alongside standard RL. The RL to SRL to HRL progression gives liner artists specific options for different line weights and ink delivery. Keep medium taper curved magnums (Red Label) on hand for artists who pack colour frequently, the blunter tip deposits more pigment per pass. Long taper curved magnums are the general-purpose shading stock. A professional shop might stock 5 to 15 different configurations depending on the range of styles and sizes the artists work. Artists who do PMU alongside tattooing need smaller-count configurations in finer diameters, stocking 1RL through 5RL in 0.25mm covers both use cases.

Single-Use Cartridges: Why Professionals Never Reuse Tattoo Needles

Tattoo needles must never be reused; each cartridge is designed for single-use only to prevent cross-contamination and bloodborne pathogen transmission. This is a health and safety requirement: check with your local health department for specific single-use and disposal regulations in your jurisdiction.

Needle sharpness degrades during a session as the needle works through the skin. Reusing a cartridge means starting with a dull needle that causes more skin trauma, less precise lines, and poor ink deposit. The artist has to work harder for worse results, and the client's experience suffers.

Single-use requirements make bulk purchasing a business necessity, not a luxury. Running out of fresh cartridges mid-session or during a busy week is not an option when every client needs a fresh, sterile cartridge. Bulk inventory ensures supply matches demand without last-minute orders or session interruptions.

Eikon does not sell products with less than 6 months until expiry; everything on the shelf has usable life remaining. Buying in bulk with Buy More Save More (10% off 5+ boxes, mix and match) keeps the per-cartridge cost as low as possible while maintaining the same quality in every individually packaged unit.

Organising Your Bulk Cartridge Inventory

Eikon cartridges come in boxes of 20, with each cartridge individually sealed in its own blister pack. Eikon's colour-coded housings make bulk inventory management practical: Purple (0.25mm), Blue (0.30mm), Red (0.35mm), visible on the box, on the blister pack, and on the cartridge base itself. Artists can grab the correct diameter from storage without reading small print. 

Organise bulk stock by configuration type first (liners, shaders, magnums), then by diameter within each type. Label shelves or drawers by configuration code (RL, SRL, HRL, RS, MG, SEM) so restocking is intuitive. Use a first-in-first-out rotation so older boxes get used before newer shipments.

Track usage patterns over time, most shops discover that a handful of configurations make up the majority of their use, with the rest pulled occasionally for specific work. Stock your core configurations deep (10+ boxes) and your specialty configurations lighter (2-3 boxes). The mix-and-match flexibility of Buy More Save More means you can hit the 5-box threshold with any combination of tattoo supplies.

Eikon's full product information, configuration codes, diameter, needle count, and taper are etched and screen-printed on every cartridge housing, readable even when the cartridge is in the machine. Between colour coding, etched markings, and consistent packaging, bulk inventory stays organised from shelf to station. Eikon keeps the full lineup in stock so shops can reorder exact configurations without worrying about backorders.

Compatible with All Professional Tattoo Machines

All premium cartridge needles we carry are compatible with all pen-style and rotary tattoo machines; the connection mechanism and housing dimensions are standardised across brands. Whether your shop runs FK Irons, Bishop, Cheyenne, the INKLAB T7, or any other standard pen-style machine, every cartridge from every brand we carry fits the same way. 

The sealed bladder membrane in every cartridge protects the tattoo machine motor from ink contamination, machine manufacturers void warranties for internal ink damage, and the sealed membrane is what prevents it. This matters especially for shops managing multiple machines: consistent membrane quality across your cartridge inventory means consistent machine protection.

PMU cartridges in smaller configurations work with permanent makeup devices as well as standard tattoo machines, offering versatility for artists and technicians who perform both services. When building bulk inventory, consider whether any artists in the shop work PMU alongside tattooing, stocking small-count configurations in finer diameters covers both use cases without requiring separate wholesale orders or tattoo kits.

Grip and cartridge fit matter: if a cartridge ever feels loose or pops off, check the grip and machine tolerances first before assuming the cartridge is the problem. A properly seated cartridge in a quality grip should click in firmly and stay put through the session. Eikon professional-quality cartridges are designed as professional tools for working artists, not as beginner tattoo kits; they're built to perform across the full range of professional machines and applications.
