Hand carvable purple wax in ring tube forms are easy to cut for creating and designing rings, cuff links, pendants, and more. Purple is the best choice for sawing and hand carving, and burns out cleanly from molds. All tubes are 6" long with a 5/8" diameter shank allowing for many rings to be cut from each tube. Dimensions: 1-1/16". Hardness: 55 (flexible).
