※ The initial product description was incorrect. It should be "Soft" instead of "Balancer." Revised 2025/12/29 100x150mm K-Series Soft GND16 With magnetic frame 100 x 150mm K-Series Soft GND 1.2 ND Filter This is a rectangular graduated ND filter. It is used by attaching it to a filter holder made by H&Y Filters. I purchased it about 3 years ago and used it both indoors and outdoors. There are some scratches and minor imperfections from use, but it should be usable without any problems. Please understand that this is a used item. It will be shipped in a cloth case.
