These Mixed Species Coaster Sets contain a great sampling of exotic woods. You will receive a Wood Species Guide Card with your set, detailing what woods were used, a short description of each species or sub-type and a coaster care card. The sides are sealed with black acrylic then coated with Marine Spar Urethane. The bottoms feature Black Vegan Pebbled Leather and the top is finished with a proprietary, locally sourced and food safe Beeswax coating; which we make in-house. We always try our best to make each coaster a visually appealing sample of the wood type used! We carry over 40 Exotic Woods regularly at this time and any of them could be featured in your set. Each coaster is carefully selected for maximum beauty, grain and clarity; then assembled by hand at our shop in Missouri.
