Coasters are 4 inches in diameter and 1/4 inch thick. Purchase a set for yourself and for a friend. We have made these sets very affordable. The Case is designed to be stackable. If purchasing more than one set, they can be stacked on top of each other without sliding off.
If you have specific images you would like in your set, please contact us directly, we will be happy to see what we can do to accommodate your request.
