Thank you for viewing. This is a set of 5 Showa-retro style food storage containers. The lid of the orange floral container is marked with "TONBO SEAL WARE." The container with the illustration on the lid is made of resin and is quite rigid. Although almost unused, please refrain from purchasing if you are concerned about slight stains or signs of use due to amateur storage. Please feel free to ask if you have any other questions. #Tupperware #ShowaRetro #Kitchenware
