Felt Bobs, also known as Inside Ring Bobs or Bangle Polishing Bobs, are precision tools used for professional jewelry finishing. Each bob is securely mounted on a wooden stalk, providing excellent grip and control while polishing the inner curved surfaces of rings, bangles, and other circular ornaments. Made from high-quality felt, these bobs deliver a smooth, mirror-like finish without scratches, making them an essential tool in jewelry polishing workshops.
