Thank you for viewing! This is a product of the custom parts brand FISHING36, which manufactures and sells custom parts for the ABU Cardinal C3. The custom parts for the Cardinal C3 are made with machined metal and matte black baked-on paint, transforming the deadstock C3 into a tactical aesthetic. We use stainless steel, aluminum, and titanium for the materials, considering their use in saltwater fishing. -------------------------------------------------------------------- FISHING36 Made C3-14691-AL Aluminum Handle Cap Screw Matte Black ¥6,500 each + ¥300 shipping (¥6,800 total) ・The knurling provides a tactical feel and excellent grip. We've designed it to tighten securely, but if it's often exposed to water, we recommend using a rubber gasket to improve water resistance. We also sell other original Cardinal C3 parts, so please follow us and stay tuned. FISHING36
