This is a Snoopy bag. I bought it a few years ago and it doesn't have the tag, but it's new and unused. The horizontal measurement is about 36 cm and the vertical measurement is about 26 cm, according to my amateur measurements. I don't think there are any noticeable stains, but it has been stored at home for a long time and it's white, so there may be some fading or oversight, so please refrain from purchasing if you are looking for perfection. I plan to fold it up small and send it via Yu-packet or Nekopos. Please comment before purchasing.
