Only USB-connected 3D pen

3D pen is the world's first pen with 3d print function. With PLA, ABS plastic, 3D pen can be written on any surface,
or even directly in the air to paint. It is very compact and does not require computer or computer software support.
You just plug it up, wait a minute,then you can start your wonderful creation.
Our company has developed a more cost-effective 3D pen, along with compact size and stable performance.
 More importantly, it uses a USB connection instead of using a charging plug, which is better for us to create anytime, anywhere.
We’re looking forward to your order.
