Plastic is the mainstream material for lunch boxes. It's lightweight, reasonably durable, and convenient to heat in the microwave. But sometimes, why not enjoy different materials and different usability? Introducing MUJI's " Aluminum Lunch Box ", which is both retro and new.


A bento box made of aluminum alloy. With the stylishness of all silver and the simplicity of MUJI, both men and women can easily use it. There are two sizes, "Large" (approx. 450 ml / approx. 10.5 x 15 x 6 cm) suitable for women and "Small" (approx. 280 ml / approx. 9.5 x 14 x 5 cm) suitable for children and light meals. .. Here are three points that I found "good" after using it.

■ Simple & stylish

After all, the simplicity that seems to be unbranded and the stylish brilliance unique to aluminum are attractive. Since there are no fine grooves or corners, it is easy to wash. The sticky greasy stains are easy to remove, giving a strong impression of scratches and color transfer. The thin and lightweight design makes it a good impression that women and children can easily carry it around.

■ With inner lid to prevent leakage

In addition to the main body, lid and partition, a polyethylene inner lid is included. Although it is not completely sealed, you can carry it with confidence if you close it tightly and fix it with a band. If you put a side dish with a lot of juice, it is safe to wrap it in a plastic bag.





There is no need to worry that the inner lid of polyethylene will deteriorate before the aluminum body due to the characteristics of the material. Only the inner lid is sold, so if you are concerned about color transfer or odor transfer, you can buy a new one. The unit price (tax included) of the inner lid is 180 yen for both "large" and "small". The price is easy on your wallet.

■ Easy to cool rice

The problem with making bento is that the stuffed rice doesn't get cold easily. If the lid is kept hot, steam will accumulate inside and cause damage to the contents. In that respect, aluminum, which has high thermal conductivity, makes it easy to cool rice and is convenient. You can reduce the time between packing and closing, so you can reduce the small stress on a busy morning.


Advantages There are various "aluminum lunch boxes", but there are some points to be aware of. First of all, it is illegal to use a microwave oven only for aluminum. Ovens and dishwashers are also disabled. In addition, boiling disinfection, long-term storage with food, and the use of cleansers are also prohibited. Without being bound by the image that "aluminum is light and durable," I want to use it for a long time after fully understanding its weaknesses. If you're not familiar with aluminum products, let your family know that you shouldn't put them in the dishwasher.

The price (tax included) is 1,690 yen for "Large" and 1,490 yen for "Small". It is small for men's lunch, so please check the capacity and choose according to the user and the situation. A "bento band" (190 yen) that helps fix the lid is also sold separately.
