Size Chart

For the Slump Hump Molds, we've used a Size moniker, such as Size 1, which in and of itself is somewhat meaningless. For that reason, make sure to check out how a size translates to actual dimensions by viewing the dimension chart of the mold description page.

In general, the larger the Size number, the larger the mold. Currently Size 1 is small to medium, Size 2 is medium to large, and Size 3 is large to very large! The duality, such as small to medium is needed since these are two molds in one; The inside slump mold is always the smaller of the two.
