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.

Estimated cooling effect (below 15℃):
When chilled food (5℃) is placed in the refrigerator, it will last for about 4 hours at an outside temperature of 25℃.

Use:
Freeze overnight in a regular freezer.
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.
