Cowhide coasters. Diameter 9.5 cm. Made from extra-thick, approximately 4.5 mm, domestically-produced genuine nubuck leather. This is tannin-tanned leather, which has been carefully tanned over time, so it will develop a rich patina the more you use it. Set of 6. If you need more than 6, please comment. Cups are not included. Please note that there may be some scratches due to the natural materials. Thank you. Material...Other
