These coasters have been lovingly stamped and sealed so they are waterproof. The coasters are 4" x 4" and also feature a full cork backing for furniture protection.
//Due to the handmade nature of the coaster, they are not dishwasher safe. These coasters are made of natural tumbled natural stone so there will be some slight variations, veining, pits and natural tumbled edges. The coasters are made to order and will be based on the coasters photographed. If you are worried about natural variation of the stone, please request a picture of your coasters in the "note" sections at purchase and I would be more than happy to send a picture of your exact coaster set prior to shipping
