I ordered a 20x24 sheet of Rosco Fire #19 to repair the filters in my Thomas Duplex. I just opened the box from B&H, and this is what I find. The entire filter looks like it was pressed between two nail beds, and there's a big crease in the middle. I can't photograph the spots, but it looks like someone went around the whole sheet with nails and made indentations with the point of the nail. There's no holes though. Is it worth returning? Will the crease or dots affect the light? I assume not, but want to be sure.
