All Cheyenne Safety Needle Cartridges contain a patented Safety Membrane, which prevents blood and tattoo ink from entering the tattoo grip and the associated cross-contamination. The shader tattoo needles are packed not as tight as the liners and can cover a larger surface area. They can pick up more ink and can be used for shading, coloring and blending. The magnum tattoo needles consisting of two rows are great for filling and shading. The soft edge magnum tattoo needles (or "round magnums") have a slightly rounded front to avoid the umbrella effect (the skin doesn't evade the needles in the middle and the design remains even).
