Laser etched slate coasters. Typically made and shipped via priority mail within 2 business days. The slate varies from 1/8th" to 1/4" thick, is approximately 4" square / 4" diameter, and has a natural chipped edge. The slate coasters are all unique due to them being a natural material, so they have different variation in the surface. These coasters have rubber feet on the bottom so they don't scratch the surface they are on. Have your own image or logo you want coasters made of? Need a large order and want a price discount?
