Sanrio 1993 The Vaudeville Duo ザ ボードビル デュオ Size: Approximately 35.5 x 43 cm I believe this is a knapsack, but I don't know the exact product name. It's a bag that closes by cinching like a drawstring, but the fabric is quite stiff, and it takes some effort to close it completely. I think it's been like that from the beginning. Please understand. This item is over 30 years old. It has been stored unused. Although there is no particular deterioration, please understand that it is quite old. Thank you for your understanding regarding long-term storage items. It will be folded and shipped in a post-size package. I have one more of these.
