Beatnik Purple RCA Tattoo Machine by Bishop Rotary

This classic Bishop Rotary machine features a design that lets you tattoo effectively for longer periods of time. The weight is distributed to flow with the tube weight, making the machine almost weightless. This helps tattoo artists suffering from wrist issues and carpal tunnel syndrome cramps.

This tattoo machine is CNC machined from aircraft aluminum and anodized to aircraft industry standards. It boasts a Swiss-made Maxon motor and a double sized “Needle Clip” feature that keeps the needle in place, eliminating the need for standard rubber bands. This machine also has a 3.5mm stroke length, which is perfect for clean line work and black and grey shading.. Each machine is assembled by hand for precise quality control.
