“Professor Origami and the Mystery of the Coastline” I'm selling this after completing it. I opened it and solved it once. This is a used kit. It's in the same condition as when I finished solving it. I think it's suitable for those who want to know what it's like. Therefore, I'm offering it at a significantly reduced price. Please understand that this is a used item. I am also selling other take-home mysteries. Please feel free to inquire if you'd like to combine shipping.
