This is a Special Edition ALL-STEEL Neuma 4. The grip, Inner Housing, and End Cap are all made from BLACK Stainless Steel. This machine has a extremely low center of gravity. Stainless Steel offers remarkable balance and stability, dramatically reduced vibration, makes tattooing incredibly easy to do, and the polished finish is beautiful. We believe that its not always about making the lightest possible tattoo machines. Sometimes its about about putting the weight in the right place.
