This is a backpack you can sit on anywhere. It seems to be currently out of stock on both Rakuten and Amazon. It's a Czech brand, so the price is high; I bought it for 34,980 yen. It has been used and has minor scratches, but no major damage. Width: 32 cm Height: 52 cm BAGOBAGO Sit-on Backpack Stool Backpack Bag Rucksack Black Large Big
