This is a coil-style magnetic tattoo machine I was just using! The brand is unknown. The coils are 10-wrap, and the back step and blue steel leaf spring power supply have been converted to an RCA jack. It has plenty of power and carves smoothly, but the hit is moderately gentle, so it has less impact on the skin. It's a versatile machine that can be used for everything from fine lines to solid color packing. I'm switching to a wireless machine, and this is the one that finished its last job today. It shows signs of use, but there are absolutely no operational problems. I want someone who understands the potential of this machine to use it!
