Cheyenne is the cartridge brand of Berlin based MT.DERM. Its Safety Cartridges have a built-in membrane that stops ink and fluid from flowing back into your machine. The round shader is grouped a little looser than the liner, for soft shading, small fills and bolder lines.
Long Taper: a gradual point that is as gentle on the skin as possible. 0.30mm (#10) is the middle ground: enough ink flow for steady work, still fine enough for detail.
This family runs in 2 needle counts (5, 7). You order per box of 20 individually sterile packed cartridges; pick the needle count you need below.
