A FACT IS: Many companies claim they're able to do 0.2mm thick glass screen protectors, or even 0.15mm, or even 0.1mm thick.

However, how can they do without the glass to be thinner than 0.1mm?

OLKTECH currently can do 0.2mm tempered glass screen protector, with the glass of about 0.17 mm thick.

And the glue of around 0.03-0.04 thick, so the comprehensive thickness would be around 0.2-0.21mm thick

But because of the extremly thin glass, it's very easy to generate defective products, hence the cost rises.

We're right now improving machine performance, and reduce the cost as much as possible.
