• MADE IN USA - we're proud to manufacture our 3x4 foam sanding pads in the USA, supporting American jobs and small businesses.
• FAST-CUTTING SILICON CARBIDE GRAIN - compared with aluminum oxide, silicon carbide grain is sharper and harder, producing faster cut rates, less sanding time, and better finish quality. 
• 1/2" THICK FLEXIBLE FOAM - the ultra low-density 1/2" thick open cell polyurethane foam maximizes flexibility and allows sanding of detailed contours and complex shapes without burning through. Ideal for cabinetry, furniture refinishing, paint work, and fine finish work.
• WET/DRY COMPATIBLE - These sanding sponges are wet/dry compatible and ideal for sanding all surfaces, including bare wood, latex or oil paint, stained wood, autobody, metal, epoxy, gelcoat, plaster, etc.

Note that because the foam conforms to contours, we catalog these by their finish quality or scratch pattern rather than the grit. Here's a handy foam grit conversion chart you can use to help select which to choose:
