☆ Perplexus Original & Epic 2-Piece Set ☆ 3D Maze that Adults Get Hooked On Products from the official Japanese import agent. Enjoy with your kids! Have fun and train your brain without any digital devices! Patience, concentration, composure, and absorption. It's all good! My child encountered the Original (pictured left) in their final year of preschool and enjoyed tracing the maze from 1 to 100, concentrating patiently over and over! You won't know until you try it, so glad I bought it! Level up in elementary school and challenge the Epic (pictured right) With an even more complex maze, their concentration and perseverance were further honed. I've bought various toys, but this is a highly recommended toy. A fun educational toy! Thank you very much.
