The slate varies from 3/16" to 1/4" thick, is approximately 4" diameter, and has a rugged chipped edge.
The slate coasters are all unique due to them being a stone material, so they have different variation in the surface, sometimes this can cause a color variation in the etching.
These coasters have rubber feet on the bottom so they don't scratch the surface they are on, perfect for protecting your tables from water rings.
The coasters come packaged in a white cardboard box, perfect for wrapping as a gift or storing
