3MK Hardy Sam S23+ S916Chemically hardened glass black

HARDY®

The toughest protection on the market

For demanding smartphone users we created Hardy®

– super hard glass that guarantees solid screen protection

against cracking and scratching.



The 9H hardness rating means that nothing will scratch the display,

except… a diamond. A bunch of keys, a handful of coins or sharp grains of sand

are completely harmless to a screen protected with

Hardy® glass.




Hardy® is more than tempered glass. Hardy® is a synonym

for quality and safety, even for the most demanding.

Hardy® glass is the ideal choice for people who use

high-quality smartphones, rely on the latest protective technologies

and want to be sure their display will always look like new.

Protects every centimeter of the screen

Hardy® adheres tightly to the screen, covering it perfectly and protecting the maximum display area. Precise cutouts in the glass ensure that the sensors and front camera remain fully functional, while being well protected from damage.




Hardy® ensures that every square centimeter of your smartphone’s screen will always be in perfect condition, no matter the circumstances.

Compatible with the latest technologies

Hardy® is a glass that’s up to date. Compatible with modern in-display fingerprint readers and Face ID on the smartphone display. The excellent touch responsiveness is thanks to the Easy Fit technology used.





Hardy® is thin and crystal clear, so it does not interfere with the facial recognition system. With Hardy®, you get the best protection in a modern and premium form.

Quick and perfect installation

You can install Hardy® quickly and, importantly, perfectly. We used Easy Fit technology, a special adhesive, so that anyone can align the glass with the screen precisely without spending too much time. The accessories included with Hardy® make it easy to achieve perfect alignment of the protective glass to the display.




Hardy® for iPhone has an additional anti-static layer that prevents dust from sticking to the screen during installation. It only takes a moment for your smartphone’s display to gain full protection against cracking and scratches.

Premium tempered glass

High-quality smartphones deserve the best protection available on the market. That’s why Hardy® was created – tempered glass heated for nearly 5 hours at 400 degrees, chemically strengthened and composed of as many as 5 layers. The manufacturing technology used ensures complete resistance of the glass to mechanical damage. That’s not all.




For full user comfort, Hardy features a high-quality oleophobic layer that provides excellent finger glide across the screen surface and high touch sensitivity. Meanwhile, the anti-microfouling layer enriched with silver nanoparticles will keep your screen perfectly clean, discreetly eliminating viruses, fungi, and mold. Hardy® also offers full image clarity and perfect color reproduction on the screen (Ultra Pure HD).
