Simply align to your webcam, attach and press firmly for a few seconds for a strong seal. Slide over to block/unblock the camera. Does not prevent laptops from closing perfectly. Compatible with most laptops with camera. Made of a mix of wheat straw and ABS plastic, reducing the need of virgin plastics.
