The 67mm Round Wolverine Magnetic Kit from Kase features three magnetic 67mm filters, a 67mm magnetic adapter that supports the filters, and a 67mm magnetic lens cap, which attaches to the front of the filters. The kit also comes with a stylish multi-filter case.
The three filters include a circular polarizer, a soft-edge graduated ND 0.9 3-stop filter, and an ND1000 10-stop filter. The magnetic adapter screws onto the front filter threads of your 67mm lens, and the three filters can interchangeably be attached to it magnetically. The filters feature multicoated shockproof tempered optical glass and metal rings.
