Castaldo Gold Label® contains even more pure natural gum rubber, making it even softer and more pliable. Experienced mold-makers know that this compound’s superior qualities can save them substantially on labor costs when used for difficult molds containing undercuts, where a stiffer mold would break delicate wax patterns or would make their production impossible altogether.
