Filters: Qty 1- No. 47 Qty 2- No. 25 Qty 2- No. 58 Qty 2- No. 96 N.D. 0.40 Qty 3- No. 96 N.D. 0.70 The filters are round cut as shown in images. The filters were given to me, but I've never used them. I haven't measured them, but the outside reads 100mm x 100mm. They appear in decent condition, some are perfectly flat while a few have some ripple/wave to them. I'll sell them as a group. or individually. Let me know what you're interested in. make an offer on all or selected filters. will sell very reasonable.
