MUJI's popular "storage container with valve" is now in the lunch box! I tried a new product, "Lunch box with valve that can be used as a polypropylene storage container," which is lightweight and easy to carry.



Made of polypropylene with a matte texture, it comes in 6 sizes. Two colors, white and black, are available. The lid is equipped with a valve and packing made of silicon material, and when the valve is pushed down, it is sealed.




Heat resistant temperature is 140 degrees. If you lift the valve, you can heat it in the microwave even with the lid on. A dishwasher can also be used.



I don't recommend liquids such as soup because it is not completely sealed, but when I put the leftover curry in it, I could carry it without leaking. Also, although the curry was not colored at one time, it is safe to choose black for those who are interested.


Fermented foods and coffee beans cannot be used because the lid may come off. It seems that it is not suitable for frozen storage of liquids, so it is suitable for foods that you can put in your lunch box.

Until now, MUJI has had few bento boxes, but the impression is that quite a few excellent items have appeared here. Why don't you take out the side dishes left over from dinner as they are, or choose a slim type for your business bag and arrange them according to your needs? * All listed prices include tax
