These are so awesome to have for your mobile phones. First off it comes with everything needed to apply to the back of your phone. Once placed on the back of the phone, and this is super easy to do, the piece acts like a stand as well, Not only can you hold it and wear it like it was a ring, making it super easy to handle, but it can be swiveled around to hold the phone at different angles in order to watch a video or whatever. Clever and easy to use. Looks really cool on as well.
