Review on Silent Pocket Webcam Privacy Stickers For Camera Lens Privacy (Black And Blue) - Blocks Hackers&#39 by Joe Lantz

Perfect for my needs. It's basically like a sticker. An important difference is that it leaves no residue and is easy to remove while glued until you want to remove it. It shows a tiny bit of white backing (I can't see it, that tiny) where you peel it off the backing when you touch it with your fingernail, but just barely. I only had to bend the back. It is good for cameras. I rearranged this once to get it in the right spot, I don't pick them up or take them off as I don't take selfies or anything.
