Wado Combo Large Square & Round Ice Cube Mold Silicone Tray Jumbo Giant Square and Sphere for Ice Ball 100% Food Grade Silicone and BPA Free(Set of 2)

I used both the cube and the orb for resin. I like that I can make semi-circles too. It is sturdy, and releases easily.

The square cubes are great, but the round mold is difficult to seal, and hard to fill. Fun novelty, but not a great design.

Makes nice round balls of ice but awkward to fill.

Awsome!!!
