9H


9H 5

Well, I managed to crack another screen protector for my phone. Time for a new screen protector.

I love how the hardness is described as 9H. I assume this is because the measure of hardness most people are most familiar with is the B – HB – H system used for pencils.

I image how the manufacturer imagines the customers to be very impressed: “9H… that’s as tough as it gets‽”
