Carvable blue (medium-hard) wax in ring tube forms are easy to cut for creating and designing rings. All tubes are 6" long with a 5/8" diameter shank allowing for many rings to be cut from each tube (1-5/16" high x 1-3/16" wide). Designed with an off-centered hole. Also ideal for cuff links, pendants, medallions, and much more! It can easily be sawed, carved, drilled, and it burns out cleanly from molds. Made in the U.S.A.
