Thank you for viewing. This is a 77mm EXUS ND16 filter from Marumi Optical. I used it a few times after purchasing it, but I don't think I'll be using it anymore, so I'm putting it up for sale. Please note that I have disposed of the case. I don't think there are any noticeable scratches on the lens surface, but this is based on my own judgment. Please understand this before purchasing. I hope you understand that this is a used item. I will pack it using packing materials to prevent any damage during shipping. Includes the instruction manual.
