Frequently Asked Questions
Most clear cases turn yellow within weeks because standard TPU reacts to UV light and body oils. Crystely's anti yellow clear case uses a treated polycarbonate case blend with UV-resistant coating, so the material stays clear far longer under daily sun exposure and skin contact. Regular cases don't have this coating, which is why they yellow so fast. If you've owned a clear case before and watched it turn amber in a month, that's oxidation, not dirt — and no amount of cleaning fixes it.
With normal daily use, a properly made non yellowing clear phone case should hold its clarity for 8–12 months, sometimes longer indoors. Outdoor UV exposure speeds up yellowing in untreated cases, but Crystely's anti-yellow formula is built to resist that. No case is permanently immune to aging, but treated polycarbonate slows the process dramatically compared to cheap TPU cases sold on marketplaces.
Yes, generally. Polycarbonate is a rigid, impact-resistant plastic that resists scratches and cracking better than soft TPU or silicone. It also doesn't stretch out or get tacky over time like silicone does. The trade off is slightly less shock absorption on hard corner drops, which is why good anti yellow cases pair a polycarbonate back with reinforced corners.
It depends on the build, not just the material. A polycarbonate case with reinforced corner padding handles accidental drops from waist height reasonably well. If you're rough on your phone or drop it often from higher up, pair it with a screen protector for full protection — no clear case alone is drop-proof.
If you keep your phone bare-back visible, yes — cheap clear cases yellow in 4–6 weeks, meaning you'll rebuy repeatedly, often costing more over a year than one treated case.
