Unused items (some opened), 4 pieces in total. Can be used for various purposes, not just lunch boxes. After use, they can be folded for space-saving portability. Recently, there was a case where a claim was made due to dirt and dust, resulting in a transaction cancellation. If you require detailed photos for confirmation, please let me know in advance. Please understand that these are used items, and those seeking perfection should refrain from purchasing.
