I am selling these items as I declutter my parents' house. These containers can be used in the microwave with the lid on. *Sizes* Medium: 11cm (length) x 15.5cm (width) x 6cm (height) Small: 10cm (length) x 14cm (width) x 6cm (height) The original box is crushed, so I will ship them in a different box. I hope someone who likes Showa retro items will enjoy them. Originally, I was selling a set of three (large, medium, and small), but since no one was interested, I am currently selling only the medium and small sizes separately. #Tupperware #FoodStorageContainers #LunchBox #ShowaRetro
