Triangular Prism Planter Silicone Mold

by Bold Molds


A sleek and modern trianglular prism-shaped mold, used to cast organizers, planters, and more. Made from premium silicone, non-stick, tolerates up to 450 degrees F, great for resin, ice, concrete, chocolate, clay, plaster, etc.

This minimal geometric mold comes with a rigid outer shell to maintain a perfect cast with straight walls. And if you like your planters to be a bit heavier, or you prefer the bulging rounded look you can always cast without the shell.
