Review on Premium Silicone Ice Cube Trays with Sealing Lid - 2 Pieces, 74-Ice Molds, Reusable Hexagonal Shape for Chilled Drinks, Whiskey, Cocktail, and Food - AUSSUA by Wendy Moore

I bought these as a mold to melt wax and I think they are good for that purpose, easy to clean and remove the melted Grow back as they harden. The lids provided do not fit the top of the mold. They just fall away. So if you want to use them I would say they are useless. They also don't last very long, so you'll probably have a hard time putting them in the freezer without spilling water all over them. I wax them and then let them cure on a flat surface, so that's not a problem for me.
