These 4" square genuine natural slate coasters feature textured edges and 4 padded feet on each coaster. Intended as coasters, we've heard of uses as mini-cheese or snack servers, and even buffet signs too. Write on them with chalk - it wipes clean with a damp cloth. You can add a laser etched monogram, too (engraving available - check for additional cost if applicable). The set of four makes a great housewarming or wedding gift. Gift boxed.
