FAQs

Currently, C1 only matches the basic, Pro and Pro Max models of the iPhone 13-15 series. Plus and mini iPhones are not compatible yet. Please check the product page for specific models.

Reink Case only supports wireless charging, but cannot be magnetically attracted. Because the magnetic ring will affect the display effect of the e-ink screen. If you really need the magnetic function, we do not recommend you to buy this product.

C1 is not waterproof. Please do not take it to bathrooms, swimming pools, beaches, etc. for use. It doesn't matter if you accidentally drip water on the phone case. Just wipe it clean in time.

Reink Case Knight is waterproof. But please do not soak it in water for too long.

The Reink Case uses a four-color e-ink screen, which contains four types of electronic ink molecules: black, white, red and yellow. The screen itself determines that the display effect of blue-purple-toned pictures will be poor. We recommend that you use it to display images with red or yellow tones. You can also choose filters with higher color saturation, such as Blues, Gothic, Lomo, etc. In this way, the final imaging effect will be better.
