Cap has been used, but it looks and works good. It is in better then average condition. It has some scratches on exterior. This Lens Cap is fully operational and functions as intended. I would rate it a 8, on a scale from 1 to 10.
Not sure what camera or lens it was made for. It is made of metal, it seems to be slip on type cap. It fits my lens with 49mm rim. Even though ID is around 48mm.
