Cowhide coasters. Diameter 9.5 cm. Made from extra-thick, approximately 5 mm thick, domestically-produced genuine nubuck leather. This is tannin-tanned leather that has been carefully tanned over time, so the more you use it, the more flavor it will develop. Set of 8. Cups are not included. Please note that there may be some scratches due to the natural materials. Thank you. Material: Leather
