Our clear cases have been designed with an anti-scratch layer on the outside, which adds a heightened level of protection but won't prevent all scratches.
However, the insides of these cases do not have this anti-scratch layer, so there is still a chance that scratching could occur if dust or grit gets inside the case. For this reason, please take care when cleaning your case or your phone, as even the tiniest dirt particles could cause scratching damage.
Please be aware that scratching is considered a wear-and-tear issue rather than a manufacturing defect so would not be covered under our Lifetime Warranty. That said, if you have an issue you think we should know about, feel free to reach out and we'd be happy to take a look!
