The Mastercraft 3 x 4 x 1” Sanding Pads 3-Pack can offer a flexible solution for fine sanding that's reusable and lasts longer than traditional sandpaper. These single-sided Mastercraft sanding pads are useable in both wet and dry conditions, and utilize a specialized abrasive grit for final sanding applications. The pads are completely reusable, and last far longer than typical sanding sheets or sandpaper. The sanding pads included in this set are available in extra-fine, fine, medium, and coarse abrasives. Measuring in at 3 x 4" (7.6 x 10 cm), these pads might not be large, but they can still provide a helping hand if you need to create a flat surface.
