This is a Familia lunch box. It was used for field trips and outings. Since it wasn't used very often, I think it's in good condition, but there's a small chip in the plastic on one side of the lid's opening mechanism. It closes properly, but when opening, you need to open it slowly, or the closing part on one side will come off. Using it by a child alone might be a bit difficult. If used with a parent, it should work fine if opened slowly. Image 6, the pink circle, is the side that doesn't come off. Image 7, the light blue circle, has a small chip and comes off if force is applied. Please understand the above before purchasing. I will ship via Mercari delivery. Thank you for looking.
