The Cheyenne Cartridge is a must have for any professional artist. Available in packs of 10 each needle is individually wrapped in sterile packaging making sure it is safe to use. A safety membrane is present in the needle making sure that pigment doesn't enter the motor so that you are safe from contamination. In return contamination can't go down the motor and into the client's bloodstream, making it very safe to use.
When the needle is not in use and power is switched off the needle point automatically retracts into the cartridge, this makes it safe and easy to change.
