Hand carvable purple wax in ring tube forms are easy to cut for creating and designing jewelry: 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).
