These are small 3/8" (1 cm) square ceramic tiles. They are about 1/6" (.4 cm) thick. These are a cornflower blue color, starting to lean a little towards periwinkle. This is a half pound of these tiles, which is approximately 220 tiles.
These tiles are UVA and frost resistant, and suitable for use in wet areas.
NOTE: These came on mesh, and I may or may not have removed them from that mesh. Some adhesive and/or mesh may still remain. Neither of these will cause an issue for most projects, but if you need to remove it, try soaking these in hot, soapy water. I would recommend testing a few first to verify your soap will not harm them.
