With this fun and professional tool, you can doodle in the air while pushing your creativity to another level without using paper. Like they always say, little things can do bigger ideas. With LIX 3D Pen, you can create anything from small to big, from details to prototypes. Melting quickly, it allows you to express your creativity on a whole new level. 3D has never been so easy.
