This set of four vintage grey rustic coasters is hand crafted using reclaimed wood. The set features a Michigan "M" inspired design that is hand embossed for a unique and durable weathered appearance before being treated with an outdoor sealer so they hold up under even extreme spills and condensation. Due to the nature of the materials and creation, all are one of a kind and a natural variation in texture and finish is to be expected and appreciated. Each measures approximately 3.5 inches square and includes protective felt pads on the underside. Coasters are sold in sets of four and designed to be cohesive, not identical.
