Castaldo® Gold Label Redi-Cuts: Jewelry Molding Rubber - 1-7/8 x 2-7/8"- 5-lb Box

Gold Label Redi-Cuts are pre-cut to fit standard mold frames, saving you significant time and effort at the bench. This organic rubber formula is world-renowned for its high natural oil content, which makes the mold self-lubricating for easy wax removal. The "Redi-Cut" format ensures 100 percent consistency in every mold you pack, reducing the chance of air pockets or thin walls. It is widely considered the finest quality vulcanizable rubber available for professional jewelry casting.
