Lee Filters Black and White 100X100 Polyester filter set. comes with No. 8 yellow, No. 21 orange, No. 23A light red and No.11 yellow/green filters. They are gel filters held in plastic frames that fit in the Lee 100 system filter holders. You can replace the filter gels if they get too banged up. The yellow filter has a couple very light scratches off to one side. The orange filter has more substantial scratches across the middle. The red and green filters are clean with no scratches. There seems to be a great deal of confusion regarding scratches on filters. The lens is incapable of even seeing or rendering even the most shocking scratches on filters. The filter is so far inside the zone of focus that the lens will never render the scratches they will blend in and you will never see them.
