Photogenic Softboxes are constructed with a durable black / silver laminated material and are complete with a handled travel bag. The spring tension rods easily fit into softbox and into the speed ring. The larger softboxes have a heat release flap, a snap-fit internal panel and front diffusion panel. The front panel is Velcro fitted allowing you to place the panel at the box edge or into the box 1 1/2" for improved light direction. No need to buy a mounting plate or speed ring, they are included with all Photogenic softboxes.
