Castaldo White Label Mold Rubber Box- Strips, 5 lbs.

These White Label rubber strips are provided in a continuous form, allowing the jeweler to cut custom lengths for non-standard mold frames. The rubber is easy to pack and flows perfectly around complex models during the vulcanization process, ensuring no air bubbles or voids. Once cured, the rubber is tough and resilient, resisting the tearing and deformation that can occur during repeated wax removals. This 5 lb box provides the versatility needed for custom jewelry studios that work with a wide variety of model sizes and shapes.
