This is a set of 62mm MC-1B, CROSS SCREEN, and FOGGILIZER filters made by MARUMI, allowing for various photographic effects. - Brand: MARUMI - Filter Type: MC-1B - Filter Type: CROSS SCREEN - Filter Type: FOGGILIZER I believe I purchased these about 30 years ago, but they show no signs of use. The MC-1B is not in very good condition, so please consider it a bonus. The C.S. and FOG. filters are in perfect condition, but please understand that they are old.
