XTREM is a customizable MagSafe phone case with a circular battery-free E-Ink screen that lets you instantly change the image on your case using your phone.
You're not the same every day. So why should your phone case stay stuck on one design forever?

It's a blank canvas for your personality—and now, a fun way to stay connected with the people you care about.
