From the Great Barrier Reef to You I'm selling this after completing it. I opened it and solved it once. This is a riddle game that was held at the Osaka Aquarium Kaiyukan. It's a used kit. It's in the same condition as when I finished solving it. I think it's for people 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'm also selling other take-home riddles. Please feel free to ask if you'd like to combine shipping. Riddle Take-home riddle Riddle kit Escape game
