The Magic Mount works on a variety of sealed, smooth, and dry surfaces! With the necessary ball head attached, the Key Light is only about 2 inches from the mounting surface. A low-profile allows positioning of the Key Light in extremely tight places. This mount has a very long-lasting, strong and washable adhesive. Think post-it note, but strong enough to hold a Key Light, and you don’t have to crumble it up and toss it when you’re done using it.
