3M BP156W9B schermfilter Randloze privacyfilter voor schermen 39,6 cm (15.6 inch)

This product claims to come with hinges for easy flipping of the screen protector, but it does not. At least, this is how they demonstrate the installation procedure after scanning their QR code. There are no instructions found with the product itself, which causes confusion. Neither is there mention of these hinges found within the descriptor page on Amazon.
