Castaldo® White Label Ready-Cut, like the strips, are made of a high concentration natural gum rubber and come lined with a white cloth on one side and a blue plastic on the other; but are pre-cut to fit popular mold frame sizes.

Packaged in a 5lb, easy dispensing box, White Label mold rubbers are the most firm of the three natural gum rubbers creating a strong, firm, yet pliable mold, making it great for all around use and simpler designs.
