Empty LEGO Duplo boxes only. Two boxes are from when I purchased Duplo sets. The other two boxes were purchased new for storage. I've changed my storage method and no longer need them. Separate sales are possible, but the price will be higher due to shipping costs. One box: 2500 yen Two boxes: 4000 yen I try my best to check them, but as it's a personal inspection, I hope you can understand. Feel free to ask for additional photos or if you have any questions.
