Set of 6 round wooden USA engraved coasters. Set comes with 2 Red, 2 White & 2 Blue 3.5" round coasters. Made from 1/4" birch plywood. Polyurethane on front and back on coasters. Item is cut using laser, the edges are burned therefore, there may be some black residue left after we clean them. The edges will be black from the burning process. Please allow for variations in wood such as grains, knots and blemishes. Also allow for color variations in stains and paints. Wood accepts these materials differently each time so no two will be exactly the same.
