Insert some creativity into your flash photography with this EZ-Flip Gel Set from Vello. Compatible with most on-camera flash units, this gel holder utilizes a strap with hook-and-loop fasteners to securely attach to the flash head and will then offer users a convenient slot for sliding in one of the thirty included gels. The assortment of different gels will allow you to take control of the color of your flash's light output, and multiple gels can be used simultaneously to create unique effects. The holder will also flip up and out of the way when you don't need the gel, and it comes with a reversible silver reflector/black flag insert that can be used to further control the light while using bounce techniques. Additionally, all of these items can be stored in the included nylon carrying case.
