Disney "Winnie the Pooh" Design Ziploc Containers Food Storage Containers Set of 4 S-size and 1 M-size containers. These were sold by Asahi Kasei Life & Living Corporation approximately 20 years ago. I think unused items are extremely rare now! (1) M-size 1 container 580ml, 155mm (length) x 116mm (width) x 50mm (height) In addition to being a food storage container, it also has a divider so it can be used as a lunch box. (2) S-size 4 containers 320ml, 135mm (length) x 80mm (width) x 50mm (height) They can be stacked for storage when not in use. The container body is transparent, and the lid is semi-transparent, allowing you to see the contents. It requires some force to open the lid. It may become easier to open with use, but please be aware of this beforehand.
