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 smaller one fits completely inside the larger 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 use them as tableware and serve food directly at the table. The lids may have yellowing due to aging. Although it's unclear if they were used, there are some scratches on the lids (images 8 and 9). The main bodies have almost no signs of use and are, in my opinion, in beautiful condition. 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.
