Look at the back of your phone. What do you see? That’s right...nothing. Half of your phone offers you zero value, and you carry it everywhere you go.

Now imagine that you saw pictures of your friends & family. Or your favorite team’s logo. Or your schedule for the day. Or your boarding passes. In other words, imagine anything that you would want on the back of your phone, just waiting there for you to see.

A Smart Case with Amazing Variability & Rich Playability

You can freely DIY the case, and change your favorite pattern as you like. One case is worth a million, and every day looks like a new phone case. 

NFC technology

No battery, no tail plug, data and power transfer via NFC. Functional requirements are met in a simpler way in order to provide a comfortable experience.

More colorful

Compared to the 3-color ink screen, the 4-color ink screen has richer colors and a more realistic display. Add an "Ink Filter" to your images to show off the unique look and feel of the ink screen.

Low power consumption

Ink screen display does not require power to maintain, the pattern will be displayed as usual even when the phone is out of battery. Only when switching patterns will draw a bit of power from the phone, with no power consumption for daily use. There's no magnetic attachment, but you can still use the wireless charger.

Adjustable lens bracket

0° to 115° free adjustment. Aluminum alloy bracket, solid riveted structure, stable and reliable. The screen and the lens are protected by a heightening. The phone is not afraid of abrasion when placed flat on the desktop, and the case absorbs damage when dropped.

Multilayer protection

Full wrap-around notch design on all 4 corners to effectively mitigate the impact of a fall. Explosion-proof glass back shell, scratch-proof and drop-proof, giving strong protection for dual screens.

Shield for e-ink screen

Tempered glass cover, explosion-proof and scratch-proof. AF molecular oleophobic coating, away from fingerprint annoyance, always keeps a fresh feel and look.
