3M Sof-Lex Contouring and Polishing Discs, Square Eyelet Center, 5/8" (0.625"), Fine, Medium Blue, 100/Pk, 1958F

These Sof-Lex Square Eyelet Center Discs are designed for contouring and polishing composite, ceramic, and glass ionomer restorations. The extra-thin profile and flexible backing with a square eyelet allow for better access to interproximal surfaces and increased usable abrasive surface. The color-coded system (medium blue for fine grit) and pop-on disc technology simplify grit identification and disc changes, helping create high-luster, natural-looking restorations.
