The HUANGER Stack Blocks (HE0225) are designed as an early education puzzle for children aged 12 months and older. These non-toxic plastic blocks feature colorful illustrations of landscapes, cosmic scenes, and various environments, providing a visual backdrop for young learners to explore. Your child can engage with the set by matching vehicle pieces, such as a rocket, airplane, car, and ship, to the corresponding cutout windows in the blocks. This process of shape sorting and stacking helps develop fine motor skills and hand-eye coordination while encouraging spatial awareness and basic problem-solving abilities. Weighing 370 grams, the set is lightweight and easy for small hands to manipulate during play.
