Kurikyu Magewappa Oval Bento Box Slim

I reserved this at a department store event several years ago and purchased it after a six-month wait.

I used it to store cooked rice, as a rice keeper, and never put side dishes in it. Aside from the dividers, I used it 2-3 times.
I always drained it and used it with great care.

There is a small dent, less than 1mm, on the surface of the lid, in the center.
Please see the 6th photo.
The dividers are unused and it comes with the original box.

Please understand that this is a used item before purchasing.
