The Vello Mini Softbox is designed to increase the quality of light from your shoe mounted flash unit. The softbox has a silver interior lining that increases contrast, and the white diffuser front creates a soft diffused light with soft shadows. It fits most shoe mounted flash units, and is held in place with the built-in elastic band. You can also use it without the diffuser front for a bare bulb effect. The softbox folds flat to conveniently fit in your gear bag.
