This is a coil-style magnetic tattoo machine I was just using! The brand is unknown. The coils are 10-wrap, and the back stem 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 gentle enough to minimize skin impact, making it suitable for everything from fine lines to solid color packing. I'm switching to a wireless machine, so this is the one I just finished my last job with today. It shows signs of use, but there are absolutely no operational issues. I want someone who understands the potential of this machine to use it!
