Microsoft Surface Pen

Tilt the tip to artistically shade your drawings — just like you would with a graphite pencil
The rubber eraser on the tail end rubs away your mistakes, just like the eraser on your graphite pencil
Writes like pen on paper, with precision ink on one end that enables tilt1 and a natural-feeling rubber eraser on the other
Sketch, shade, and paint with artistic precision and finer control with 4,096 pressure points that respond to the lightest touch
Ink flows out in real time with no lag or latency. No matter how fast you’re writing or drawing, the ink flows directly from the tip of your Pen to your screen
