This is a Zuppa de Zucca dinosaur backpack. I bought it for the retail price of 5000 yen. The size is just right for children aged 1-2 years old. I started to think it might be too small when my son started wearing size 100 clothes. I've used it 3 or 4 times, and it's in almost perfect condition. I think it's still very usable, so please consider it if you're interested.
