Thermos Bento Box 2-Tier Slim Fresh Lunch Box With Insulated Bag 815ml Navy Check Purchased several years ago and used a few times for lunch, but the portion size was too small, so I switched to a different lunch box quickly. It has been stored in a dark place since then. The lunch box, chopsticks, and lid gaskets still show no signs of deterioration or dirt. I would like to sell this to someone who understands that it is a used item. Returns and complaints are not accepted.
