Eco-friendly material, non-toxic and harmless: These building blocks are made of high-quality eco-friendly plastic. They are non-toxic, odorless, and pollution-free. Precision craftsmanship, exceptional quality: Each block is meticulously polished, with smooth, rounded edges and corners, free from burrs or defects. The blocks fit together tightly and smoothly, ensuring a seamless building process while also creating sturdy, stable structures that are unlikely to collapse. Enhances hand-eye coordination: During the building process, children must use their small hands to accurately grasp and place each block. This process significantly enhances their hand-eye coordination. From picking up a block to precisely connecting it in the correct position, each action requires close coordination between the eyes and hands. With continuous practice, children's hand-eye coordination will improve significantly.
