Carvable green (hard) wax in ring tube forms are easy to cut for creating and designing rings. All tubes are 6" long; therefore allowing for many rings to be cut from each tube. Outside diameter measures 1-1/6" with an off-centered 5/8" 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.
