Specifications: Meet Microsoft Surface Pen. Write and draw naturally. Create without limits. Writing and drawing on your Microsoft Surface device with Surface Pen feels natural, with precision ink on one end and a rubber eraser on the other. Sketch and shade with artistic precision—the 4,096 pressure points respond to the lightest touch. Tilt the tip to shade your sketches just like you would a pencil, using one of three different tips. No matter how fast you’re writing or drawing, the ink flows from the tip of your Pen to your screen with virtually no lag. When your Pen is low on power, replace the battery quickly and continue to let your creativity flow.
