XTREM Instant Custom E-INK Case for iPhone 18 Pro Max

Your case will never look the same twice

The XTREM Instant Custom case is an iPhone case with a screen built into the back. Send any image – a photo, logo, anything to it using the app. Change it as often as you like.

Make it yours

Pair the case with your phone. Take a photo or choose one you love, then tap “Cast Image”. It will appear on the screen in just a few seconds.

Great protection

Real drop protection and a real cutout for the camera — nothing has been sacrificed for the screen. The case is compatible with MagSafe.

No battery. Ever.

There is no battery in the case at all. Once the image is set, it stays there permanently – even after the case is removed from the phone, thanks to E Ink technology.

No battery needed. Ever. Surprised?

The XTREM case has no battery – at all. To change the image, the case draws a tiny amount of power through NFC, the same wireless technology used by Apple Pay, consuming even less energy than a single contactless payment.

Once the image is set, it remains on the screen permanently – whether the case is on the phone or not. Photos have a soft, printed look, resembling a photograph more than a phone screen. Faces, pets, logos, and simple graphics look great.

Everything happens in the app

• Take a new photo or choose one from your album

• Choose from hundreds of ready-made designs

• Turn any photo into new artwork with the Remix feature

• Connect with XTREM cases belonging to family and friends and send photos directly to their cases

• The app is constantly evolving – new features and fun ways to use the case keep appearing, so there is always something new to try
