KANI Wide Reverse GND 0.75 150x170mm square filter. I no longer use filters, so I'm offering this to anyone who wants to try it. There are no noticeable scratches, but it's used, so please forgive any oversight. The box has scratches, etc., so I've marked it as "used." - Model: Wide Reverse GND 0.75 - Accessories: Comes with a case - Size: Filter size 150mm x 170mm To prevent replacement fraud, returns are not accepted. Thank you for your understanding. I plan to list another one.
