I displayed it for a short period and have kept it stored at home since. I believe there are no noticeable stains, but please understand that this is a used item and only purchase if you are comfortable with that. Size: Approximately 33cm x 33cm I plan to slightly deform it and compress it for shipping via Yu-Packet Post. If the size is too restrictive, I will switch to Rakuraku Mercari Delivery and use recycled cardboard for shipping. Please be sure to understand this before purchasing.
