This ring is truly fun! The myriad resistors, sprinkled with some vintage capacitors and diodes, move as your hand moves so the patterns and colors are ever-changing. It’s also a fun conversation piece for those in the electronics field, as well as those who don’t even suspect what this riot-of-color ring is made out of. The silver colored band is adjustable to fit most sizes. Contact me if you need something extra big or extra small and I can most likely accommodate you.
