Thank you for viewing. This is an educational toy, an interactive puzzle maze, where you move balls in numerical order. I took it out of the box and used it a few times that day, for a total of about 30 minutes. The box is also clean. I bought it for my 3-year-old son, but he wasn't interested in it at all. It's suitable for intelligent children, curious children, or as a gift for birthdays or Christmas. I hope someone can use it. - Product Name: FUNNY GEAR LABYRINTH DISK - Target Age: 3 years old and up - Features: Interactive puzzle maze - Colors: Blue and orange - Function: Move balls in numerical order - Brand: Puzzle Maze
