Just the right shape

The vertical shape fits well and can be carried without tilting. In addition, the side dish has a partition, making it easy to serve, and is recommended for those who do not want to mix rice and side dishes. Each container has a capacity of about 500ml, making it the perfect size for growing children and men. Both the top and bottom containers have separate lids, so they can be used separately.

Comes with gasket to prevent leakage

Each lid has a silicone rubber gasket, and the two-tiered lunch boxes are firmly secured together with a rubber band. Even if you put in a slightly juicy dish, it is unlikely to spill, so you can carry it around with peace of mind. *It is not completely sealed, so if the food is juicy, some liquid may leak out.

Corners are easy to clean

The corners are rounded, making it easier for the sponge to reach every corner and leaving no 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.
We also have slim rectangular lunch boxes.
