Review on Red Devil 3318 Plastic Sandpaper by Christopher Clearfield

Cheap plastic holder. Works well on flat surfaces for short jobs. The two halves stay together thanks to tabs on the bottom that fit into the top. It doesn't work well, but if you hold it tight, it stays on. The sandpaper holds very well as it is held in place by the small spikes that you slide the sandpaper over. It's probably better to pay a little more for a more comfortable rubber grip.
