Thank you for looking! This is the Logical Route Puzzle that I bought a few years ago, and my children played with it! o(^▽^)o I'm selling it because my children have grown up. All the pieces are included(^^) There is also a problem book. The outer box is also included, but it has aged over time. There are some stains, so would you be interested if that's okay ♪(ᴖ◡ᴖ)♪ Logical Route Puzzle KUMON Educational toy Toy Kids
