Tokyo Discovery 2025 This is a sticker from a puzzle event created by QuizKnock. I participated in the puzzle-solving with a friend and received this sticker, but I haven't used it and have just been storing it. I'm looking for someone who would like to have it. It's a sticker of Mr. Sugai. Available for immediate purchase. The price is set with reference to other listings. There was an error, and it was listed as "cash on delivery." Shipping is included. I have changed it. By the way, the puzzle-solving was a lot of fun!
