Each coaster is 4 1/4” square, ¼” deep and made from ceramic tile. I have used acrylic paint pouring techniques to create an abstract design and added 2 coats of StoneCoat resin for high gloss and protection, along with a full cork backing. They are UV and heat resistant to 500 degrees F and food safe.
Each set of four coasters is $58 including shipping + tax.
