I am listing this item as I am decluttering. This item was a gift and has been stored in my kitchen storage without being used. As there were no diagrams for assembly, I assembled it once for the purpose of this listing. This is a set of 2 cute folding lunch boxes with bear illustrations. When folded, they become about 1.5cm thick, making them convenient for carrying home. The inner dimensions of the main body are approximately 12.2cm x 9.3cm, and the height is about 6.5cm. Although it has been stored for a long time, it was kept in a dark place, so there appears to be no deterioration or dirt on the main body or lid. The box has a slight discoloration. I will ship it with waterproofing measures, including the box. If you do not need the box, please let me know in the comments. Thank you for considering this item if you understand that it has been stored at home.
