This is simply a replaceable inner ring for the EWA MagOne 3rd Gen Cell Phone Ring Holder Kickstand, which must be used in conjunction with the EWA MagOne 3rd Gen Phone Ring Grip Stand and cannot be used independently. Why have we designed the inner ring of our EWA MagOne 3rd Gen Cell Phone Ring Holder Kickstand to be replaceable? Because our third-generation product uses an elastic strap as the band, which can become deformed and dirty over time. By making it detachable and replaceable, it allows users to refresh the product as if it were new. Additionally, users can choose inner rings in different colors to match their products, meeting a variety of personalized needs.
