• 10mm MEDIUM DENSITY FOAM - the medium density 10mm thick open cell polyurethane foam is excellent for flat sanding yet flexible enough to avoid burn-through. Perfect for shaker doors and light hand sanding edges on cabinetry, furniture, and painted surfaces.
  
• 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:
