This is unlike any sandpaper I've ever used before. It's really flexible with a rubbery feel backing. Great for sanding bisque as it conforms to the shape of the pot really well :)
I just received my package from Diamond Core and a piece of this sandpaper was included. I had just finished firing a glazed load and one cup had some rough spots on the lip and this sand paper took care of it right now - quick. I love how flexible it is and did not damage the glazed area around the problems. I am definately ordering more.
