2 years & up. All Aboard! This little engine will have children on track for learning! Just a little imagination and they can custom build their own train from the 15 interchangeable pieces and three linking cars with sturdy pegs for joining cars and stacking "cargo" blocks. A must for any toddler as it encourages the development of color, shape and size recognition, spatial concepts, fine motor and problem solving skills. Measures approximately 17" x 6" x 3".
