VectorMoon Stereoscopic 3D Printing Pen for 3D Drawing and Doodling - Kids and Adults - 1.75mm ABS/PLA Filament (Purple) DRAW YOUR DREAMS! Replace your old pen and paper with the new and improved VectorMoon 3D printing pen. This pen heats plastic to its melting point, creating the perfect consistency for drawing on paper, clothes or even off of the paper in the air! NEW AND IMPROVED SLIM DESIGN! Compared to its competition, VectorMoon's 3D printing pen is much slimmer to better fit the contours of the users hands, young or old. INCREASE YOUR USAGE TIME! With other 3D pens on the market, the user must hold the extrude button down in order to draw. VectorMoon's 3D printing pen enables a double tap to continuously extrude until toggled off. FULL ADJUSTABLITY! VectorMoon's 3D printing pen has both a temperature dial and speed control in order to fine-tune to your specific preferences. THE ONLY LIMIT IS YOUR IMAGINATION! With all colors of 1.75mm filament available (3 rolls of which are included with purchase), anything you can think, you can draw and bring to life!
