This is an upgraded version based on the optimization of the previous 3D printing pen, which adds the consumable storage function, and no longer needs to drag a tail line to become a real pen.
At the same time, we have also optimized the shape, improving it to a cute shape, and children will like it more
In addition to maintaining high performance and durability, the set comes with some practical tools, such as an atlas, drawing paper, etc., to make it easier for children to get started.
