The 49mm Magnetic Cap Kit Pro consists of top and bottom magnetic steel caps for non-threaded 49mm Kase magnetic filters. Attaching to both sides of a filter when the filter is removed from a lens, these caps protect the filter from dust, scratches, and fingerprints. They can also be used the same way with multiple magnetically stacked filters. The caps protect the stack from the top and bottom while allowing for safer and more efficient storage and transport of the stack.
****PLEASE NOTE**** Works only with Kase 49mm Magnetic Filters. Will NOT work with ordinary Non Magnetic Filters.
