Blue Light & UV Protection

Long days on your screen add up, and blue light along with UV exposure is a big part of why your eyes feel tired by evening. ULTRA HARD GLASS keeps the same full 0.4mm Dragontrail® Pro glass from AGC as the rest of our lineup, with a UV and blue light filter built into the glass itself — so you're not trading away clarity or durability to get it. The structure also holds up noticeably better against cracks, so everyday drops and knocks are less of a worry.

Seamless Curve x Perfect Fit

Thick and strong is one thing, but ULTRA HARD GLASS also gets the details right. The edges are shaped with a generous curve, so there's no awkward lip catching your finger mid-swipe — it just feels smooth, the way a well-made watch crystal does.

And because it's cut to sit flush against your iPhone's display, it doesn't look like an add-on. It just looks like part of the phone.

Why We Skip the Thinning Process

Most tempered glass protectors go through a slimming step after the raw panel arrives from the factory — grinding it down to the final thickness before shaping. The problem is, that process can weaken the glass before it even reaches you.

We skip it. ULTRA HARD GLASS uses the panel at its original 0.4mm thickness, then goes straight into heat tempering and surface treatment, keeping Dragontrail® Pro's full structural integrity intact.

Less processing, less damage, more strength where it counts.

Precision-Cut for iPhone 18

Every panel is laser-cut specifically for the iPhone 18 series — same display dimensions, same cutouts. Face ID, the front camera, all your sensors work exactly like they should, with nothing in the way.

Smooth Surface x Anti-Glare Comfort

On top of the anti-smudge coating, this version adds an anti-glare layer — so glare from overhead lights or being outdoors doesn't wash out your screen, and fingerprints still wipe off without much effort.

If the glass does ever crack, a built-in film helps hold the fragments together instead of scattering, so it stays safer to handle.
