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).
