Holds plenty

The capacity is 760ml, so even a man can pack a sufficient amount of rice. It is recommended not only for women, but also for growing children and men. It has a partition so it is easy to serve, and you can separate rice and side dishes, or use it as a bento.

Comes with gasket to prevent leakage

The lid is fitted with a silicone rubber gasket and a rubber band to securely fasten the lunch box in place. Even if you put in a slightly juicy dish, it won't spill out, making it safe to carry around. *It is not completely sealed, so if the food is very juicy, some liquid may leak out.

Easy to wash

The round shape of the lunch box makes it easy to wash every corner without leaving any residue behind.

Made from durable stainless steel

Made of durable, rust-resistant 18-8 stainless steel. It is resistant to the odor and color of ingredients, so you can use it for a long time.
Small lunch boxes are also available.
