Review on Flexible Spill Resistant Removable Chilled Cocktails by Kate Woods

The hexagonal shape makes the base very strong despite being made of resilient material. I used to have molds made out of this material, but they are fragile and cannot be stacked inside each other. This product is thick enough on the sides to hold its shape when stuffed and moved/lifted. The only downside I can think of is the lid, it's very soft and thin and just sits on the base (doesn't snap in place). Still works like a case but very soft.
