The patented Eyebloc Magnetic Webcam Cover for MacBook is the thinnest webcam cover on the market, allowing your MacBook and MacBook Pro to close completely while attached. It attaches using the laptops built-in magnets, so there is no residue from tape or stickers. To use, simply place the cover over your camera and slide to expose your webcam. Eliminates the risk of the screen cracking or trackpad damage caused by bulky plastic webcam covers. Designed specifically for MacBook, but also works with any magnetic laptop screen.
