Tupperware, an oval, airtight storage container. They can be stacked. Because they are the same shape, you can choose your favorite lid colors. There are various sizes; the medium size is suitable for storing powders, opened sugar, salt, cornstarch, granulated dashi, dried kelp, etc. The small size is suitable for spices, bouillon cubes, etc. It is also recommended for storing butter in the refrigerator. You can remove the lid and put tubes of wasabi or mustard in the refrigerator, and it's convenient to take out the container as a whole. There are various ways to use it. Sizes: 13 x 9 x 12 cm, 1100ml 13 x 9 x 6 cm, 500ml 13 x 9 x 4 cm, 300ml 13 x 9 x 3 cm, 200ml I found these in the kitchen shelves while organizing my parents' house. I selected the ones that looked clean. The orange and blue lids have some scratches that appear to have occurred during storage. The bodies also show some slight discoloration, but I think they are relatively clean. Please check the photos. Please understand that these are used items, stored at home, and are products that have aged over time before purchasing. Thank you for looking.
