This is a nostalgic Showa-era reproduction. I always buy these, but I end up not using them and they just sit in my dresser. However, I'm in a situation where I need to declutter, so I'm putting them up for sale. I hope someone will cherish them in my place! Since it comes with a box, the shipping cost will be higher, and the price will be increased accordingly. Box size: 28cm x 21.6cm x 5cm Lunch box size: 14cm x 9cm Unopened, so the thickness is unknown. Thank you to the 3 people who have liked this! Please purchase soon! Thank you very much for looking!
