Kase K9 90mm Red Lens Cap (3 pack)

These Kase K9 Lens Adaptor Caps are to be used with the Kase K9 90mm filter system. They are made from flexible plastic and they click on over your metal adaptor rings to protect your front lens glass element. These caps are necessary if you permanently attach an adaptor ring to your lens as your original plastic lens cap will no longer fit.
