1" wide, 4cm thick Bi-color (red & white) foam water pushers. This is a great way to push water and make a lot of noise undewater like a struggling fish. These heads also help turn your fly on every stripping pause to provide a full profile shot of your offering to the predator of your choice. Simply use a bobkin or the like to the center of the foam head to start a hole and slide it over the eye of your fly. 5 water pusher heads per bag.
