Each coaster measures 4 inches in diameter and is a little over 1/2 inch thick. Because each coaster is poured by hand using silicone molds, there may be little differences from one to another. The one(s) you receive may be different than those pictured. There may be slight imperfections such as bubbles or fibers which I try my best to eliminate but some are impossible. They do not take away from the overall beauty of the coaster. Coasters were created using Artresin. A clear, non-toxic resin. This price is for one coaster only.
These coasters are hand made by me using resin by ArtResin. ArtResin is non-toxic resin that is safe for food contact. The heat generated from a hot mug will not damage the resin surface. However, hotter temperatures such as that produced from a frying pan or casserole dish straight from the oven may well be too hot for the resin surface, so I do not recommend coasters be used for hot plates. Hand wash using warm water and gentle soap.  ArtResin is recommended for use up to 120° F. Resins tend to yellow over time. Store in a dark place when not in use.
