3M Sof-Lex Contouring and Polishing Pop-On Discs, 3/8" Diameter, Medium, Dark Blue, 85/Pk, 1981M

Sof-Lex Pop-On Contouring and Polishing Discs feature an extra-thin, flexible urethane-coated profile for precise finishing and polishing, including hard-to-reach interproximal surfaces. The color-coded, pop-on system simplifies grit identification and disc changes, while the low-profile mandrel design maximizes usable abrasive surface. Suitable for finishing and polishing composite, ceramic, and glass ionomer restorations, they can be used wet or dry with a low-speed handpiece.
