Put water in and freeze it and use it as a cooler for a cooler box.

Almost completely filling the water, frozen while keeping the lid, and using it in the cooler box is used. Even if ice melts, the cooler box does not drain, it is repeated in the freezer and it is reused. The product is sturdy and high in transparency, and it is wonderful! Until now I bought a plate ice at a convenience store, but even after frozen after melting, the shape collapsed and it became a problem without becoming useless. I have been able to solve many years' troubles, I am happy going to mountain stream fishing and Ayu fishing. Why would not everyone use it instead of board ice? Thank you for a wonderful product.
