The Glass Screen Protector for FUJIFILM GFX 50S II from Expert Shield is a hard tempered glass with a silicone gel layer for easily attaching it to the camera's rear display. To remove it, you can just pull up a corner of it with some sticky tape (not included). The glass is near-perfectly clear, meaning you won't notice any reduction in your screen brightness or any dulling in image sharpness.
Included with the glass shield is a Crystal Clear shield for the top LCD of the camera. It will protect this small LCD from scratches while providing full see-through visibility. It secures to the camera by "dry fit" attachment. Just place it on the display without any adhesives or anything else required.
