Dura-Block 7 Piece Sanding Blocks - DuraBlock
Product Review (submitted on December 2, 2010):
I had a couple of DuraBlock sanding blocks that I have used for a number of years. Their blocks are great. They have just the right amount of flexibility and work wet or dry. I purchased the seven piece kit to fill a need for different sizes and shapes of blocks. I would recommend the kit to anyone.
