This mold is designed so you can freeze water to keep your recovery going smoothly. We found that water bottles and ice packs dont fit well, and the fridge cannot keep up with generating ice. You can put the ice in with the whole mold, or you can break the ice free. Both will fit just fine. They are stack-able too, and have a lid as an option so you dont spill while placing in freezer.
There is a thinner version good for PETG, which allows for flexing to release mold, or standard that should be made from TPU.
The author marked this model as their own original creation.
