The 77mm Center Pinch Snap-On Lens Cap from Flic Film is a front lens cap with a center pinch, spring, and snap-on mechanism. It is easy to put on and take off, and it stays on. Lens caps protect the front element of a lens from scratches, fingerprints, and the elements when the lens is not in use. It's always good to have a spare in your camera bag, too.
