Our Marble and Acacia Wood Coaster Set adds the perfect blend of elegance and functionality to any kitchen or bar. The wood can be laser engraved with your message or logo. The coasters are made of natural materials making them beautiful and unique; each coaster wood will slightly vary in color. Foam dots can be found on the bottom of the coasters to help with slipping. To maintain their quality, wipe with a damp cloth and mild detergent.
