It's absolutely brilliant. The website was easy to use, and the image on the case is printed clearly and perfectly. I normally go to a different website to get my phone cases, but I'll be coming back here in future if I need a new phone case.

My case arrived exactly as I had designed it. I'd been looking for ages for a company that did this. My wife now wants one.

Really great quality! Use on my phone everyday dropped a few times by accident but no scratches or cracks or any damage! Love it and definitely recommend it, fits perfectly
Katie3 months ago
The phone case I ordered was even better than expected. Very good quality material, the image looks great, and it's also a tough and protective case. The order also included postage and it arrived very quickly too, so an absolute bargain. I chose to print one of my own artworks on the case so it's a bit of a promo tool for me when I'm out and about, loads of people have commented on how good it looks! Would highly recommend DesignMyCase.

Excellent quality and perfectly designed case for my pixel 9. Was a little worried when the website preview showed a different camera cut out, but it came through as the correct case with my custom made design printed really well on the back. Crazy good value for money!

iPhone 18 bumper case features

Slim TPU bumper, full-colour back panel, edge-to-edge protection where it counts.

Edge-to-edge coverage

The bumper wraps every edge of the phone where drops actually do damage, with cutouts that line up cleanly with the ports and buttons.

Lightweight and durable

About 3 to 4mm of total added thickness. Drop protection where the phone meets the floor, slim everywhere else, no brick-in-pocket feel.

Extreme grip

The TPU bumper has a subtle texture that fights the natural slipperiness of polished glass-back phones. Easier to hold one-handed.

Top-quality materials

Colour-stable TPU on the bumper, flat polycarbonate back panel so the print stays saturated and undistorted. Built to feel premium for the life of the phone.
