ACER AMERICA - OPTIONS Works with Chrome USI (Universal Stylus Initiative) Rechargeable GP.STY11.00L

This stylish silver stylus from Acer supports more than 4000 levels of pressure sensitivity, to give you a drawing and writing experience similar to that of pen-on-paper.
Plus, weighing in at a mere 21 grams, it's light enough to use for extended periods of time without discomfort.

The stylus is also USI compatible, meaning it will work with any compatible USI device - these include the Acer Chromebook Spin 513, Chromebook Spin 514 and Chromebook Spin 713 (CP713-3W).
