Cool!t coasters are made from surplus ceramic tile. You can use Cool!t as a coaster for drinks and they can also be used as a pot holder together or separately. When using four to six pieces, Cool!t can be used under a bigger casserole or when using four they can be used under a baking tray, in all four corners. Coasters can be cooled in the freezer to keep food and drinks cold. Silicone buttons on the bottom, so countertops won’t be harmed. Cool!t can be used as a candle holder. Shades of grey may vary.
