This is an Animal Dept. lunch box. I took it out of the bag for the photos, but it will be shipped in the original bag. It's a two-tiered lunch box, but it can be stored as a single tier. Diameter: Approximately 10cm Heat resistance: Inner lid 70°C, other parts 140°C Microwave safe (Please refer to the instructions for details, such as removing the lid.) It's new and unused, but please understand that it has been stored at home.
