Frequently Asked Questions
What Is A Curved Magnum Tattoo Cartridge?
A curved magnum uses a two-row zig-zag needle structure — the same as a regular magnum — but the needle grouping is precision-formed into an arc. That arch follows the skin’s natural contour, distributing ink more evenly across the contact span. The result is smoother gradients, softer edges, and less trauma compared to a flat magnum. The arched design mimics a Filbert paintbrush, which is why curved magnums are also called Soft Edge Magnums.
What Is The Difference Between A Curved Magnum And A Regular Magnum?
A regular magnum uses a flat, straight two-row configuration — its squared corners tend to leave a harder edge imprint. A curved magnum bends those same rows into an arch, eliminating the sharp corners so ink distribution softens along the edges. That is the defining performance difference: curved magnums excel at smooth blending and soft transitions; regular magnums are more versatile across bold fills and harder-edged shading.
What Does Contact Span Mean And Why Does It Matter?
Contact Span is a REBEL innovation — it defines the exact width of skin surface the needle grouping touches and marks in a single pass. REBEL is the first in the industry to define needle groupings with this level of precision. Because different gauges can produce overlapping contact spans (a 15CM in #8 Bugpin covers nearly the same surface as a 13CM in #10), contact span is a more reliable guide than needle count alone when selecting the right cartridge for your shading coverage.
What Is Bugpin And When Should I Use #8 Versus #10 Gauge?
Bugpin refers to the gauge — the diameter of the needle wire — not the taper. REBEL Bugpin is #8 (0.25mm), a fine gauge with a long taper. The finer wire allows needles to be soldered closer together, producing ultra-fine transitions and smoother blending with reduced skin trauma. The standard #10 (0.30mm) is a medium taper gauge — it deposits ink faster and covers ground more efficiently, making it the better choice for larger shading areas and color packing. Taper and gauge are two different things: taper describes the sharpened tip length; bugpin describes the wire thickness.
Which Curved Magnum Size Should I Use For My Work?
The 11, 13, 15, and 17CM configurations are the most popular — they balance precision and coverage for black & gray, portraiture, and color work. For larger pieces and seamless multi-color transitions, 19–27CM configurations are the better fit. The 35CM and 45CM Giant configurations are built for maximum coverage. If you work with fine transitions or sensitive skin, the #8 Bugpin configurations (9–15CM) give you the most control. Use Contact Span — not needle count alone — to compare configurations across brands.
Are REBEL Curved Magnum Cartridges Compatible With My Tattoo Machine?
Yes. REBEL Precision Curved Magnum Tattoo Cartridges are compatible with all standard cartridge machines and grips — rotary, pen-style, or any machine that accepts standard-diameter cartridges.
Are REBEL Cartridges EO Gas Sterilized?
Yes. Every REBEL Precision Curved Magnum Tattoo Cartridge is EO gas (Ethylene Oxide) sterilized and individually sealed. EO sterilization is the gold standard for single-use tattoo equipment — it penetrates blister packaging without heat or moisture, ensuring sterility without compromising the cartridge components.
What Are Curved Magnums Not Suitable For?
Curved magnums are not designed for linework or tight corners. Their arched configuration excels at shading, blending, and large-area color packing — but for crisp outlines and fine detail, you need Round Liners. They are more specialized than regular magnums in that sense.

Compare to previously used cartridges we have been using at the shop, REBEL has better working properties like ink distribution, surface covering and the ability to create soft gradients

I have a special love for these cartridges. I have been using these for a few months now and I honestly don’t think I will be switching over to any other brand. Each artist has their own way of figuring out which needles and configuration works best for them. From the first time I used these needles I was hooked. Allowing me to do better line work while also bettering my color packing and helping to create those smooth transitions of tones in black and grey. My favorite/go to needles are for sure the 11 curved mags!!!

These mags are great for packing in solid fields of color and the soft edge makes fading out or blending to another color nice and smooth. They also work great when shading out black and grey tones. No tracks or stripes at the edges, just soft grey tones.

I have been through every needle made to date always looking for the best,,,,, look no further these needles are the BEST I have ever used, consistency, precision, best grouping. I have switched 100% to rebel something I have never done. I have always used a liner from A. shader from B , now im all REBEL$!!!

We are a REBEL distributor and the REBEL curved mags our best seller after their liner. Our tattoo artists are loving the new BUGPIN versions with the long taper and #8 gauge steel pin. They are saying that they can do a much smoother color or shade transitions because the smaller guage needles are closer together and holds almost the same amount of ink as #10.
Go ahead and try them out!
