Question about 4smarts Pencil Pro 3

The "Pencil Pro 3" stylus from 4smarts has not been specially developed for the iPad Air 2. The iPad Air 2 does not support Apple Pencils and most modern styluses are designed for newer iPad models. If you are looking for a stylus for the iPad Air 2, you might consider using an older stylus like the Wacom Bamboo Fineline, which connects via Bluetooth and offers pressure sensitivity.
