Easy to use sanding block. Designed to be compatible with 5 inch discs, but also works with sandpaper sheets. 5 inch discs do not need to be trimmed, and the excess on the sides can simply be folded up onto the side of the sanding block.
Can't wait for my father in-law to open this Christmas present tomorrow morning! He's been refinishing furniture as a hobby the last couple of years so I think this will be a good addition to his toolset.
