Klar-Guard™: Clear, Forever.

Because a Clear Case Should Stay Clear.

Clear cases look incredible on day one. Then comes the problem everyone knows: sunlight, heat, skin oils, sweat and everyday use gradually turn many clear cases yellow.

We decided that wasn’t good enough.

So we developed Klar-Guard™ Anti-Yellowing Technology for the new CoreX — engineered to preserve its crystal-clear appearance through the conditions a case actually experiences every day.

And because CoreX was built for the Emirates, we didn’t stop at ordinary laboratory testing.

We pushed it further.

What Is Klar-Guard™?

“Klar” means clear in German.

Klar-Guard™ represents our approach to protecting the original look of your iPhone without hiding it behind colour.

For the latest CoreX, we took Klar-Guard™ further than ever before, focusing on resistance to the main factors that cause clear cases to lose their appearance over time: UV exposure, heat, oxidation, perspiration and everyday environmental stress.

The result is our strongest clarity promise yet:

Crystal clear. Backed for life.

Every new CoreX is backed by a Lifetime Anti-Yellowing Guarantee.

Tested Far Beyond Everyday Use

We didn’t design Klar-Guard™ around ideal conditions. We tested it for the conditions that clear cases struggle with most.

  • Extended UV & Heat Testing
    CoreX undergoes prolonged accelerated exposure to intense UV and elevated temperatures — for significantly longer periods and under harsher conditions than our previous Klar-Guard testing — to evaluate long-term colour stability and resistance to yellowing.

  • Tested in UAE Heat
    Laboratory testing alone wasn’t enough. CoreX has also been subjected to real-world conditions in the UAE, where extreme heat and intense sunlight create one of the toughest everyday environments for a clear case.

  • High-Perspiration Wear Testing
    We deliberately included users whose hands create an especially demanding environment for clear cases. Some of these testers typically see ordinary clear cases begin to yellow within just 2–3 weeks of daily use.

    CoreX was put through the same real-world daily wear so we could evaluate Klar-Guard™ against sweat, skin oils, heat and continuous hand contact — not just conditions inside a laboratory.

  • Extreme Temperature Cycling
    Klar-Guard™ is tested through repeated temperature changes to evaluate the case under thermal stress and ensure clarity and structural integrity are maintained across demanding conditions.

Built for the Emirates. Tested for Real Life.

A case doesn’t live inside a laboratory.

It sits in your hand. In your pocket. In the sun. In the car. It encounters heat, sweat, oils and countless hours of everyday use.

That is why we believe anti-yellowing shouldn’t simply be a claim printed on a box.

It should be a promise.

The Clear Case Worth Waiting For.

The new CoreX combines the clarity of a clear case with protection engineered for everyday life — including up to 3 m drop protection and Klar-Guard™ technology backed by our Lifetime Anti-Yellowing Guarantee.

Your iPhone was designed to be seen.

CoreX keeps it that way.

Precision. Protection. Perfection.
