It’s an iPhone 14 Pro clear case with MagSafe

The warranty doesn't cover user damage. But, if you think that the damage is the result of a defect, contact Apple and discuss if it is replaceable under warrant. Start with the Support link at the bottom left of every page of this forum.

What do you mean? You damaged a case on your phone? You’ll need to buy a new one.
