Yes, this pen is simple and the lowest-priced 3d printing pen in the world. You might wonder, did you compromise on quality since it's so low-priced? The answer is no. We are able to make this 3d pen at such a low price because we discarded the screen, and by making it compatible with computer USB port and power banks, we discarded the power adapters, too.
Although there is no screen with this 3d pen, the led lights on the front side tells everything about the pen.
Make better profit with this lowest-priced 3d pen now.
