Snaps in place, attaches securely to camera lens.
"I've purchased several Spigen products for every smart phone I've owned. I really like how well they fit and perform over time. This lens protector installed very easily. You just remove the protective backing, place the lens protectors over the camera lens, and press each lens protector down onto the lens. They quickly and securely snap into place. They have a QR code on the box to watch their installation video that is very helpful as well. These lens protectors fit and work very well with my Spigen case too. I have used this for 1 month now and haven't experienced any problems with them coming loose. I am very pleased with my purchase and would highly recommend these lens protectors."
