Important Notice:

Due to possible variations and inconsistencies in third party manufacturing and the iPhone models, Cupert does not warranty damages caused by cases and bumpers, even those on our case compatibility list. Cupert conducts its own tests and cannot guarantee consistencies in third party production.

When installing a case/bumper, make sure the lip is properly aligned over CINDER. If not properly aligned, CINDER will be lifted resulting in hazes.
If a haze does occur: Use a thin piece of plastic, place it between the lip and CINDER, and slide it slowly along the parts where the lip isn't properly placed.
When installing a bumper, we recommend to always to install it from above your iphone and not below, as the last method can catch the edges of CINDER, making CINDER lift and, in the worst case scenario CINDER can crack.
