The former answer is wrong! anti-scratch 3H means that, using 3H pencil to do the scratching test on the hardness tester for pencil, the force on the touching point of the pencil and the film is 500g.
It's similar to pencil 3.0 H, meaning hardness degree is 3.0.
It means that there will be no scratches on the surface of the film! The price is about three times than that of OK8. The cost effectiveness is quite high. But the performance is not good!
