Featuring updated hardware and tilt support, the surface pen (2017) from Microsoft is compatible with select Surface products and provides you with a pen on paper like drawing and writing experience. It now has 4096 levels of pressure sensitivity with virtually no lag, and can now be used to shade in your drawings as you would with a pencil. There is still a side button for quick access to shortcuts and commands, as well as a tip eraser for a natural workflow. For more customization options, you can change out the tip to one that fits your style (sold separately). The surface pen pairs to your device wirelessly via Bluetooth 4.0 and is powered by a single AAAA battery.
