GamiLight BOX 21 (best flash diffuser rating: 8.60) is a new portable softbox from Gami Light Concepts, a Malaysian manufacturer of hot shoe flash accessories. With its size of 8.5"x6" (21.5cm x 15.5 cm), BOX 21 is suited for on- and off-camera flash photography applications. It is built after its big brother, SQUARE 43, using the same high quality materials. Both diffusers share the same design principles including detachable front screen, silver lining, snap system, and being able to fold flat.
BOX 21 folds flat, and it is easy to fit in your gear bag. It actually has few snap buttons inside to ensure that it stays flat when folded.
