Stigma-Rotary® Ray Pen Tattoo Machine — Designed for accuracy and precision, the Stigma® Ray is a pen-style tattoo machine that allows artists to have total control during the tattoo procedure. Easily adjust the stroke length from 3mm to 4mm by turning a screw on the machine, or configure and leave it on your preferred setting if you don't like to make stroke adjustments. The Ray features the hex-drive system and is recommended for use with the Stigma® 6W MotorPlug.
