FAQ

Product

What is the difference among diverse series?

・Privacy (Black) Film
Utilizes micro-louver technology. Offers exceptionally high light-blocking properties. The screen is only visible when viewed directly from the front.

・Clear (Transparent) Film
Made with high-transparency PET substrate. Does not block external light, allowing it to pass through freely. Maximizes the screen's original vivid colors and brightness.

・Anti-Reflective (AR) Film
The surface is treated with a reflection-reducing coating. Maintains screen clarity while making it easier to view, even in bright conditions.

・Blue Light Blocking Film
Infused with special light-absorbing agents. Absorbs and cuts off the blue light emitted from the screen, helping to reduce eye strain.

How to apply the screen film perfectly?

① Clean the screen thoroughly before you start. Any dust or residue can cause bubbles, so be sure to wipe it down carefully with the included cleaning cloth.

② Secure the alignment tool firmly around all four corners. To prevent lifting or shifting, make sure the phone is held steady and each corner clicks into place.

③ When pulling the protective film, place your palm flat on the alignment tool and pull slowly — keeping it parallel to the screen at all times.

What if it lifts or bubbles appear after application?

Gently press bubbles out with a soft cloth, from center to edges. Small bubbles usually disappear within 1–2 days. If it doesn't improve after a few days, contact us for a replacement.
