I finally found a cylindrical sealed container with a diameter of 12 cm and a height of about 7 cm. Burger style instruments It is very handy when bringing lots of sandwiches. There is no moisture leak, it is easy to wash up to the corner even after use, it is a perfect product. From now on, if the container part is opaque and version of favorite color comes out, I will buy it. I appreciate the assortment of Monotaro!
