Description

From the seller
Rock tumbler machine. Lets you create jewelry like keychains, bracelets & more. Bring out your inner scientist (or keep the kids busy in the best way possible 😄)! ⏳ Note: The process takes a few weeks—but that’s part of the magic (and honestly, it’s kind of addictive watching the transformation happen).
