A highly functional lunch box that functions as a cooling agent when frozen by sealing an ice pack inside the lid. After filling it with food, just place the lid, which has been frozen overnight in a household refrigerator, in place. By freezing the lid and using it, the lid itself acts as a cooling agent, so you can carry it around safely even on warm days.

When chilled food (5℃) is placed in the refrigerator, it will last for about 4 hours at an outside temperature of 25℃.

Use:

In the morning, fill it with food and simply set the frozen lid in place.

Remove the lid and pop it in the microwave! It's safe and delicious to eat.
