Newly Launched: 4-Way Privacy Version

Featuring the all-new Japanese AGC® Dragontrail® Pro glass

“ULTRA HARD GLASS for iPhone 17 Series” is made with AGC® Dragontrail® Pro glass.
By utilizing the original glass material at approximately 0.4 mm thickness—without undergoing thinning processes that may compromise strength — it delivers exceptional durability that surpasses conventional tempered glass screen protectors. Compared to the previous Dragontrail® X, the enhanced stress layer provides improved toughness and greater resistance to impact, making it less prone to cracking.

Each screen protector is also treated with a special anti-smudge coating, helping to resist fingerprints and dirt while making cleaning easier than ever.

After leaving the glass factory, screen protector glass is typically thinned during processing to achieve the desired thickness, which can reduce its original strength. With Dragontrail® Pro, the 0.4 mm ultra-hard glass retains its original strength by deliberately avoiding the thinning process. Instead, advanced precision processing and thermal curing techniques are applied, achieving the perfect balance between touch sensitivity and impact resistance.

“DIY Alignment Tool” for effortless, zero-mistake installation

Easy to apply, with a smooth and responsive surface finish

The surface is treated with multiple coating layers, providing a smooth, pleasurable glide for your fingers and an exceptional touch experience. At the same time, it effectively resists dirt—fingerprints, oils, or makeup residue can be easily wiped away. Thanks to a special film treatment, even if the glass breaks, fragments will not scatter or cause injury.
