Variable ND filter, NANO D Series, perfect for adjusting light intensity. This is a used item, but there are no noticeable scratches. Thank you. I have checked that it can be smoothly attached and removed (both front and back) by fitting it to other filters. There is no case, but I will pack it carefully to prevent breakage before shipping. Thank you. - Type: ND Filter - Series: NANO D Series - Variable: Variable ND Filter #ndfilter #k&f #camerafilter Thank you for viewing.
