If you like to take photos, you probably have a camera that has a tripod mount on the bottom. Your camera likely also has the ability to change out lenses, which means that you have to deal with lens caps during shooting. They get tossed in your pocket, left in your car, or worse; dropped on the ground, never to be found again. Trying to keep track of those things can be difficult, unless it’s attached to your camera.

There are cameras that have the lens cap attached with a string, but it always gets in your way. This is why the Stow-Away Lens Cap Holder is such a simple, yet ingenious idea. It will keep track of your cap so you won’t have to. It can hold cap sizes of 52, 55, 58, 62, 67, and 72mm, and screws into the the standard tripod mount with a thumb screw. One of these in flat black will cost you about $14, and a special edition one in green will cost $20.
