Kobo Aizawa ｜ Deep lunch box

This is a "deep lunch box" made by Aizawa Workshop, a manufacturing studio in Tsubame City, Niigata Prefecture, which is world-famous for its production of stainless steel products. The deep lunch box can hold 2-3 deep fried chicken pieces stacked together, so it is recommended for those who want to eat plenty of rice and side dishes. In addition, the lid with a silicone rubber gasket and two fasteners provide a tight seal, so you can safely carry food with a strong smell or ingredients that are slightly juicy.

Plenty of depth

The lunch box is about 7cm high and deep, so you can fit plenty of rice and side dishes inside. 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. Also, because it is deep, it is recommended for bento boxes where you put side dishes on top of rice. It can be used by a wide range of people, including men, women, and children.

Tightly sealed and leak-resistant

One of the attractions of Kobo Aizawa's lunch boxes is how airtight they are. The lid is fitted with a silicone rubber gasket, and two additional fasteners secure the lid to the main body. Even if you put in a slightly juicy dish, it's unlikely for anything 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.
