Great collection of correction, - effects filters with slight weaknesses ...

A very good and extensive film collection, which leaves nothing to be desired. The sheets are kept in a small bowl of transparent, thin plastic. Each film is embedded with a paper and the associated number and a graph (more for professional use). Unfortunately, the film itself is not marked, so a great care by the user is required to maintain this order.
The films are also very thin and does not seem to be particularly heat resistant. My YN560-II has managed to deform the film after a few flashes so strong that I thought that the film blows soon. Therefore, a film holder is highly advisable. I have only attached by a small rubber before lightning - my mistake.
I hereby would like to only point out those little weaknesses before buying, because these were me before buying is not even known.
The color effect is, however, illuminated very clean and it's fun, so get creative.
