Thank you very much for viewing. This is the "Kenko PRO1D R-Cross Screen (W) 72mm". I purchased it new about 3 years ago. I used it once for nightscape photography and then stored it in a dehumidified storage box. It's a very beautiful product, like new. I am selling my lenses this time, so I am offering it for sale as I no longer need it. Size: 72mm I am sorry, but I do not accept immediate purchase or price negotiations. Please bid only if you agree with this price. Thank you.
