It is compatible with any aXtion case and connects with the included keyring to the shoulder strap port located on the corners of the case. For use on a case without a built-in stylus holder, the tether is paired with a 3M stylus holder which can be adhered to a non-porous surface. The holder features an elastic loop, which secures the stylus when not in use.
