Abrasive discs developed by 3M especially for jewelers. Each flexible plastic disc is color-coded to denote grit. No compound is necessary, grit is uniformly dispersed throughout the disc. You work faster and clean-up is that much easier!
Use for cleaning, pre-polishing, blending and removing scratches and firescale. Excellent for gold, silver, copper, pewter and brass. Discs can be used singly to access tiny or hard-to-reach areas. They can also be stacked to make a thicker brush for covering large surface areas.
