Diamond Sanding Pads are great for finishing off edges of bottles or any glass surface. It also works great with fused glass projects that have a few glass spikes that need to be dealt with. Keep the Sanding Pad wet while using it on glass.
Each sanding pad has a plated diamond abrasive surface that is permanently glued to the semi-flexible foam support pad. Pads measure about 4-1/4″ x 2-1/2″ x 1-1/4″.
