Castaldo Silicone Mold Strips - 5 lb. box


Silicone has the consistency of modeling clay or putty, which means there is no need to cut and shape the pieces, just pack the silicone into your mold. Molds are firm, and cut like butter. No spray release needed due to the anti-stick compounds. Low temperature metals such as pewter can be cast directly into silicone molds.
