The Cokin filters per se need you still nothing to write, they are just great! Unfortunately, one saves now the Hard Case which was formerly part of each filter! My last filter I bought many years ago and now I wanted to broaden my sentence to a filter. Upon delivery I was very disappointed, because the filter is supplied only in the illustrated cardboard sleeve! Therefore, I give only 3 stars because that forces me now to me to buy a separate filter bag!
