## Description

It effortlessly transitions into a lively canvas tailored to your preferences. This is more thana mere case; it's a bold expression of your individual style. However,we hope you can understand the shortcomings of the ink screen.The ink screen we use is a black, white and red three-color screen,it can display simple black and white pictures better, obviously. , it cannot compare the color，Pixel and clarity with LCD screens. If you saw some ink screens display the same pictures as LCD screens, it is untrue. How To Use ink Case?

Review: Unique - So simple to use. Good quality and I love how you can easily change the photo whenever you like. The fact that you don’t need to charge is is a plus.
Review: Amazing Change - Love it, its amazing and you can change it all the time you want depending on the day. It doesn't require or have energy so It doesn't shine at night. TIPS: I usually have my ID or a credit card or UNO card (like in the video) between the phone and the phone case, and it also changes the picture even though there is something in the middle. IMPORTANT: It doesn't work with Magsafe (Iphone 14 Pro Max), if you want one that work with Magsafe, there is another one called: NFC Magsafe Support.
