This is a general use flash diffuser/softbox for most of the external flash including Canon 580EX/430EX II, Nikon SB600/SB800/SB900, Sigma EX EF 530 DG ST/EX 530 DG Super and Nissin Di866/Di622/Di466 and Woctron 2800DSF flash. There is a silver colour reflective surface in the diffuser, therefore you may use this diffuser as a bouncer if there is no suitable bouncing wall around. Users may create different light effect by turning the diffuser mounting on the flash. 

Note: The actual product does not include the flash shown in the image.
