Soft-Sanders are designed to sand almost any shape, and each Soft-Sander Block has been designed with a purpose. These pliable blocks fit comfortably in your hand and are extremely durable. The tapered edges of the blocks allow you to sand up to and underneath those hard to access places, while the smooth contours and soft edges virtually eliminate gouging. The kit contains six blocks of different shapes and each of 2-3/4" x 5" sheets of 80, 150 and 180 grit SuperFlex sandpaper.
