This is Tupperware, made in Japan. Size: Main body: Approximately 18 x 18 x 5 cm (large) Main body: Approximately 9 x 9 x 3.5 cm (small) The small one fits completely inside the large one with the lid on. Opens and closes smoothly. Made in Japan Tupperware. Country of origin: Okazaki City, Aichi Prefecture. The square shape and the color and material are lovely, so you can serve food directly on the table using them as tableware. The lids may have some yellowing due to age. It is unknown if they were used, but there are some scratches on the lids (images 8 and 9). The main bodies are in almost perfect condition, and I think they are beautiful, but this is my personal opinion. Please understand that these are items stored by a private individual before purchasing. I'm sorry, but I cannot offer a discount due to the cost of shipping and handling.
