ECO111 ECONOSIC SILICON CASTALDO

Castaldo No Shrink Pink Strips Mold Rubber contains pure natural gum rubber, making it softer and more pliable. This Castaldo Strip has absolutely no shrinkage, and high adherence to detail and memory. Experienced mold-makes know this rubber has superior qualities that can save them substantially on labor costs. A stiffer mold would break during delicate wax patterns, but this rubber mold is perfect for containing those difficult undercuts and delicate wax patterns.
