I've been using a sticky note to cover the camera

I’m not so sure charging almost $5 for three of them is a deal, as a piece of tape or something else can cover a camera for free, however, these are unobtrusive, easy to install, don’t show all that much, and the little part you slide to close or open is more efficient that removing and replacing a piece of tape or part of a sticky note

I got this because I have been using zoom for work/school this year and it has been SO convenient, I used to have to use a sticky note but this has been so amazing for covering up my webcam really quick or covering it when I am done with meetings for the day

Easy to apply, sturdy, and doesn't fall off like sticky notes
