3D Printing Pen
That's right, it's like drawing but in 3D! You'll have hours of constant entertainment with this! Uses ABS plastic, which almost all 3D printers use. It comes with filament but you can easily reorder more from anywhere. 3D printing technology is new and often overpriced. The people in china love it though and they already have plenty of suppliers competing for low prices! Now you can get this same technology for a cheap price.
