These didn't turn out quite how we wanted..... the varnish has slightly cracked during the drying process, but these are still 100% useable! Each wooden coaster is 3.34" (8.5cm) in diameter and are chunky at 0.40" (1cm) thick, with a waterproof varnish finish. All coasters are supplied in sealed packaging. Occasional dark markings may occur, which is just the natural composition of the wood.
