Magnum Tattoo Needles - Magnum Tattoo Needles

What Are Magnum Tattoo Needles?

Magnums feature a two-row stacked needle configuration that creates wider coverage than round needle groupings. The stacked geometry is what makes a magnum needle cartridge unique, and it's what makes them the tool for colour packing, shading large areas, and soft blending work.

The sealed bladder membrane inside each cartridge acts as the needle's return spring. It pulls the needle bar back after each stroke, and a consistent membrane gives consistent recoil from the first cartridge to the last. The sealed design also prevents ink and blood from reaching the pen-machine motor, meeting sealed-system requirements where mandated (check your local health board for specific rules).

The stacked arrangement delivers more ink per pass than a single-row round needle configuration. Broader contact area with the skin, more pigment laid down with each stroke. This is what makes magnums the tool for colour packing first, with gradient work and smooth shading following from the same geometry, the wider contact zone blends transitions evenly across the surface.

Magnums are available in needle counts from 5M up to 27M across the major magnum needle cartridge brands, with Kwadron's Combat Magnum line extending up to 89 needles for very large-area work (backgrounds, solid colour fills, full panels). Larger counts cover more surface area per pass for efficient background work; smaller counts give more control on detail shading.

Curved vs. Straight-Edge Magnum: Understanding the Difference

Curved magnums (also called soft edge magnums, SEM, or sometimes round magnums in supplier shorthand, all the same configuration) arrange the two needle rows in a gentle arc. The centre needles extend further than the outer needles, creating a forgiving tip that moves smoothly around body contours like shoulders, ribs, and arms without catching edges.

Straight-edge magnums (also called standard magnums or mag shaders) keep the same two-row stacked construction but with a flat profile instead of an arc. The sharp edges provide precise control for working against lines, shading into corners, and geometric designs where defined boundaries matter.

A note on terminology: "Round magnum" is a common search term, but it's not the standard technical name for this configuration. The proper terms are soft edge magnum (SEM) or curved magnum. Supplier naming varies: Kwadron uses "Soft Edge Magnum," Cheyenne uses "Magnum SE," Eikon uses "SEM," and some brands use "Round Magnum" (RM) in their product codes. These are the same product under different labels.

Most professional shading artists stock both curved and straight-edge magnums in their preferred sizes. Curved for the everyday shading slot where forgiving edges matter, straight-edge for specific work where defined boundaries earn their place.

Magnum Tattoo Needle Configurations: Complete Guide

Magnum needle counts range from 5M (tight detail shading) through 7M, 9M, 11M, 13M, 15M, and up to 27M for broad coverage work, with Kwadron's Combat Magnums extending the top end up to 89 needles for the largest panel fills. Odd counts are standard because they give symmetrical coverage across the two rows.

Standard 0.35mm diameter magnums deliver bold colour saturation and cover efficiently for most shading applications, while 0.30mm offers slightly finer control with less trauma per strike. Some brands (Eikon's SEM line, for example) also offer 0.25mm bugpin magnums for the finest gradation work.

Long taper is standard for magnum cartridges. It enters the skin with less resistance and less trauma per strike compared to medium or short tapers, producing the smooth colour application that shading work requires. Medium taper is available in select curved magnums (typically larger counts) for colour packing work where the blunter tip holds more pigment at the point of contact.

Stacked two-row magnum construction is the modern standard across both curved and straight-edge magnums. Single-row flat shader configurations, a different product, are nearly obsolete in cartridges because the two-row stacked geometry delivers more consistent ink distribution and wider coverage. What is the difference between a magnum needle and a flat needle? Magnums use a two-row stacked configuration; single-row flats use one row of needles arranged side-by-side, similar to round shader needles, and are now rare in modern tattoo supplies. 

Top-Rated Magnum Tattoo Needle Brands

Eikon Cartridges — Eikon's own magnum line covers both Curved Magnums (SEM) and Mag Shaders (MG). SEM is the deepest configuration in Eikon's cartridge range, 20 total configurations across all three diameters (Purple/Blue/Red = 0.25mm/0.30mm/0.35mm) with long and medium taper options on the larger counts. MG (flat-edge mag) comes in 0.35mm for precise edge work. All Eikon cartridges carry colour-coded housings that identify diameter at a glance from the box to the cartridge base. For artists working traditional bar-needle setups alongside pen machines, Eikon's Hydra line, Eikon's own bar-needle brand, also carries soft-edge magnums, so Eikon covers the magnum slot across both cartridge and bar-needle formats.

Kwadron — Kwadron's magnum lineup is the broadest in needle-count range: 12 soft edge magnum counts (5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27) in #10 (0.30mm) and #12 (0.35mm), with long taper standard and medium taper on select configurations. Kwadron's product language emphasizes "soft edge and superior ink flow" and "even distribution of pigment." Artists who want the widest selection of specific counts typically reach for Kwadron first. Kwadron also produces a separate Combat Magnum line (straight-edge, high-count) going up to 89 needles for large-area coverage, a distinct product from the Soft Edge Magnums above.

Cheyenne Craft Cartridges — Cheyenne offers both standard Magnum Craft Cartridges (5-magnum through 17-magnum counts in 0.30mm and 0.35mm, long taper) and Magnum SE (Soft Edge) Craft Cartridges for curved-edge work (7, 9, 13, 17, 23 SE counts). Built on 304 medical-grade stainless steel with Cheyenne's Patented Safety Membrane (US 8,029,527). Cheyenne describes the SE arc as designed to "avoid the umbrella effect", their term for unwanted ink spread on contoured work.

Lotus Cartridges — Lotus brings a full range of curved magnums and standard magnums to Eikon's lineup, built on premium Japanese 316L stainless steel, individually checked at a 99.8% perfection rate. Eikon is the official and exclusive Canadian distributor for Lotus. 

TEX Cartridges — TEX (made in Canada by Deadly North) offers magnums in their cartridge lineup with a distinctive artist-designed angle and biodegradable packaging. 37 total configurations across the TEX range primarily in 0.35mm with long and medium taper.

Magnum Needle Capabilities: Shading, Colour Packing, and Lining

Magnums are built for shading and colour packing. The two-row stacked needle arrangement spreads ink across a wider surface than a round needle grouping, which is what makes magnums efficient for broad saturation work, and also why they aren't the tool for crisp linework. 

For gradient shading and colour blending, curved magnums distribute ink evenly across the arched tip. The geometry does the blending work that a straight-edge configuration would require more compensation to achieve. Smaller counts (5M-9M) suit detailed shading and tight spaces; larger counts (13M+) efficiently cover larger surfaces.

For colour packing, larger magnum counts (15M-23M) in 0.35mm standard or medium taper curved mags deposit more ink per pass. The blunter tip on medium taper holds more pigment at the point of contact, which is why Eikon's Red Label SEMs are available in medium taper on the larger counts specifically for colour packing work.

Artists today have plenty of options — brands like Cheyenne, TATSoul Envy Needles, Sovereign, and Rebel Precision each have their following in the magnum market. Eikon's collection carries the brands our team has vetted for professional performance in Canadian studios. 

Can you line with a magnum? It depends on the artist and the work. Round magnums produce soft, diffused marks, some artists use them for "whip shading" effects that blend lining and shading in one pass. Artists working primarily on large-scale pieces (sleeves, backpieces, large-format panels) often line with magnums to keep a single configuration through the piece, a practical choice driven by the scale of the work. For crisp linework on smaller pieces or detailed work, round liners remain the dedicated tool because their tight grouping and stabilised needle travel are built for sharp, controlled lines. Eikon's Round Liner progression (RL → SRL → HRL) covers the range of linework needs, see the Tattoo Liner Cartridges collection for the full lineup.

How to Choose the Right Magnum Needle Size

For detailed shading work, soft portraits, and tight spaces, smaller magnum counts (5M-9M) provide precision while still covering more area than a round shader. The counts most artists reach for on detail shading and transitions between shaded sections.

Medium magnums (11M-15M) are the workhorses for most shading applications, offering the balance between coverage efficiency and detail capability across traditional, neo-traditional, and Japanese styles. These are the counts most shading artists keep stocked at the top of the rotation.

Large regular magnums (17M-23M) excel at background fills, large-scale colour packing, and covering significant surface area quickly, the right choice for back pieces, sleeves, and other large-format tattoos where pass count matters.

Count matches the area: larger configurations need more machine power to drive (surface tension scales with needle count), which is why some artists switch machines between detail and background work. Consult your machine manufacturer's recommendations for starting points rather than prescribed voltage or Hz numbers.
