Our coasters are designed and produced by us in Brooklyn, NY. We use a laser cutter to cut and engrave the maple plywood, and we finish the product by hand. These coasters are stained and sealed to protect them from all water/moist stains. You won’t have to worry about their durability. The set of four coasters includes a branded muslin bag, making them the perfect gift for any house warming party, birthday celebration, or for any dog lover.
