Thank you for viewing. I am selling this item to clear out my parents' house. This is a fancy, Showa-retro two-tiered lunch box. Both the lid and the body are heat resistant to 110 degrees Celsius and cold resistant to -20 degrees Celsius. The material is plastic. The upper tier has a mesh design. Size: 15cm x 15cm x approximately 5cm high (per tier) I have included an image of a sample lunch in the end, please take a look. It would be nice for a spring picnic with your children. The outer box is slightly deteriorated. Please consider it as packaging material.
