This is an unopened lunch box that was a purchase bonus from petit main (プティマイン). I am selling it because I have no plans to use it. ⭐︎Brand new, unused, unopened ⭐︎Microwave safe ⭐︎Color: Beige, Capacity: 1900ml, Large size (The instruction manual in the enlarged photo says 57cm, but this seems to be an error. Actual measurements are approximately WxDxH = 17.5x14x13.5cm). Good for picnics, etc. ⭐︎Since it is unopened, I haven't checked the contents, but according to the instructions, it seems to have a gasket.
