This is a small envelope (pochibukuro) featuring a crane folded from a single sheet of origami paper. As shown in the fourth photo, it's the perfect size for a business card. It also seems like it could hold about three folded bills. Perfect for New Year's gifts (otoshidama), Christmas, or greetings. I think people from other countries would also appreciate it. I don't remember how to fold it anymore... Please understand based on the photos. Thank you.
