After much research on the net, I was looking for a proper product quality and convenience and there I think I found a small price 5 "diffusers 1" with a carrying pouch that is no longer than 25cm in diameter and therefore that we can stay in the camera bag. I just receive it (thank you Amazon for shipping celerity) and unpacking've enjoyed the finish, the seams are of good quality and remains to be seen after N + 1 uses if closures Lightning hold up because there deeux trundle packaging. I think this is the ideal format for portrait and macro photography, what I (the) intended.
