Thank you for viewing! This is a product from fishing36, a custom parts brand for the ABU Cardinal C3. We manufacture and sell custom parts for the Cardinal C3, using machined metal and matte black baked-on paint to give the deadstock C3 a tactical look. We've chosen stainless steel, aluminum, and titanium for the materials, keeping saltwater fishing in mind. -------------------------------------------------------------------- New, Unused ¥2,200 / Set of 3 Includes shipping for ¥2,500. * The screw length is 8mm to fully engage the depth and prevent loosening. * I use these frequently because I fish in the ocean and perform maintenance often. * A 2.5mm hex wrench is included. We also sell other original Cardinal C3 parts, so please follow us and check them out. fishing36
