This is a stuffed animal cap by the artist peichan, also known as ぺーちゃん. It was a semi-custom order item at a pop-up shop, where you could choose the patch and the stuffed animal. I purchased it several years ago, so there are some small stains and yellowing around the edges. Please refrain from purchasing if you are concerned, as it is white. I remember buying it for around 12,000 to 13,000 yen. Color: White系 (White-based)
