It is not Tempered Glass but a FILM as you can see in the video I uploaded. It is important for the title to represent the product.
However, the most significant problem is not that, I would be fine even with the film if it stuck at least. Once I applied it, it came off the next day. I have applied films and glasses before, I know the process, but this specific product is of poor quality. I don't know if I received a defective one, but it was completely dry on both sides and wouldn't stick at all.
I do not recommend it.
