Filter  has been used. But glass looks very nice, I don't see any large/noticeable scratches. But filter has couple tiny hairline scratches from use. Damage is minor. Filter is in very good condition over all.  Threads look good. I would rate it at 8 out of 10, Filter is in better then average condition over all. 

Please make sure that your lens has 40mm threads (it might not fit 40.5mm lenses).  Filter is threaded.
