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 liner is for line work: outlines, contours and lettering. The needles sit in a round grouping, which keeps the line tight and closed.
Super Long Taper: an extra long, gradual point for the finest, crispest line. 0.35mm (#12) gives the most ink flow: the diameter for bold lines, traditional work and fast fills.
This family runs in 4 needle counts (3, 5, 7, 9). You order per box of 20 individually sterile packed cartridges; pick the needle count you need below.
