Delicate Smooth Oleo-phobic Coating Treatment

The fingerprint problem is really annoying because it reduces the visibility of the screen. In addition, there are problems such as water spraying and dripping oil, which make the situation worse.

But these things don’t happen in OTAO tempered glass screen protector.So the typing and touching the phone surface are much easier and hassle-free.
We use plasma spraying and electroplating processes to evenly spray the fingerprint oil imported from Japan on the glass film to achieve a lasting hydrophobic, water- and oil-repellent effect.

Strongest Glass Screen Protection

The aluminium-silicate glass and the tempering technology used in OTAO Tempered Glass to increase the surface tension of the glass making the full body stronger.

Maximum Scratch Protection

OTAO Tempered glass uses premium glass material and special hard coating treatment.So it prevents most of scratches in daily life by such as blades, scissors, keys and other hard, sharp objects above the ground scraping.

Bubble Free & Dust Free

In order to save costs, many factories produce in a non-dust-free environment, and it is easy to absorb dust into the product AB glue, and some dust is difficult to be found if it has not undergone strict quality inspection after production, until they are attached. You can see it on the phone, it’s too late.

Some factories use low-quality AB glue, and air bubbles may also appear.

OTAO adopts high-standard quality inspection procedures, from raw materials, production environment, production process to final storage, strictly controls, and delivers a qualified dust-free and bubble-free tempered glass screen protector to you.

9H hardness

Please note that 9H in the tempered glass industry actually refers to pencil hardness, not the well-known Mohs hardness (Pencil 9H Hardness = Mohs 6H Hardness). Each batch of OTAO tempered glass needs to pass the strict Japanese Mitsubishi 9H pencil load hardness test.
