Kobo Aizawa ｜ Oval lunch box

The long, oval-shaped lunch box fits easily into the bottom of your bag. It can be used by women, children, and men alike. The lid with a silicone rubber gasket and rubber band keep the lunch box firmly in place, so you can carry it safely even if it contains strong-smelling or slightly juicy food.

Comes with dividers for easy serving

It has a divider, so it's easy to serve and is recommended for those who don't want to mix rice and side dishes. The capacity is about 570ml, so it can be used not only by women and children but also by men.

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 juicy, some liquid may leak out.

Corners are easy to clean

The rounded ends make it easy for the sponge to reach every corner and ensure no dirt is left 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.
In addition to the oval shaped lunch boxes, we also have rectangular and slim rectangular lunch boxes.
