I really like them. They are similar to sandboards but have the grit of sandpaper suitable for woodworking. I use them for sanding dollhouse pieces and have recently started using them in dry and biscuit stage ceramic projects. Sanding waste comes in a variety of sizes, shapes, and textures. Very diverse. I keep them in a mug by my workbench and they come in very handy for complete finishing work on small pieces of wood. They are well put together - thicker and stiffer than nail files. If I had one negative comment (and I really don't have that), perhaps the range would be more varied. Many of mine seem to be very coarse grained with less fine grained ones. But it's all good and I encourage you to try them.
