Color Changing Geode Slice Coasters, Thermal Changing

This set of coasters was made with a thermal pigment that changes the coasters to a blue color when exposed to heat/sun. It's a beautiful sparkling black, topped with stunning silver holographic chunky glitter.

Each coaster has tiny little rubber bumpers underneath to protect your surface. The coaster is made with epoxy resin.

**These coasters are not dishwasher safe. Do not soak in water. Just wipe down with a damp dishrag is all that's needed.**
