The Wolverine magnetic front lens cap can quickly and easily snap on to either a Kase Wolverine magnetic adapter ring or filter, and helps to protect the filter and lens against dust, moisture, and scratches.
Please note: Due to the design of the Kase Magnetic filters, the Wolverine lens cap should be used with the Wolverine filter system only. A Kase Skyeye front lens cap should be used with the KW Revolution system.
