At first glance, the cheapness like "disposable" is cute. I bought a container called "Colorful Frozen Storage Pack" sold by IMOTANI.
A container that can hold a bowl of rice (about 200g (7.05oz)) and side dishes. Although it is thin and weighs only 12g (0.42oz) per piece, it is compatible with both frozen storage and microwave ovens. The lid is designed so that the front and back can be turned over, and it is convenient to use it properly for freezing rice with the concave side facing up, and for carrying side dishes and fruits that are easily crushed with the convex side facing up. Since it can be stacked and stored, it is also a point that it is difficult to take up space in the refrigerator or lunch bag.
Actually, when I looked at the product photos before purchasing, I imagined that it would be a little too cheap. However, when I picked it up, the pattern was pretty cute, and it was a good impression that it was light and not bulky. However, it may be mistaken for a "disposable container", so it may be safer to say a word to people around you, such as your family. A set of 6 is priced at 500 yen (excluding tax). How about using it for food preservation, casual lunch boxes, and carry-on parties?
