This is a set of 5 Christmas coasters made on ceramic tiles. I use very fine shiny glitters to get that shimmery effect. Each coaster has a cork finish on the bottom.
If you happen get any dents from too hot mug(some mugs have very thin bottom), just use hot air from the hair dryer and resin will come back to its flat state.
Set of 5 square coasters 4"x 4" come with a mini easel for a nice display, and a wooden box.
