This is a spare hook for a Bin Bin Switch. These are custom-made, two-hook rigs with a stepped design. This is a bulk purchase of 5 sets. The hook size is Maruto's Ise-Ami hook, flat-ground, size 10. These hooks are domestically produced and chemically sharpened, ensuring very high quality. They use black nickel plating made in Japan, which is highly corrosion-resistant. To prevent line breakage, the line is Sea Ride size 10, slightly thicker. These are made with reference to the Bin Bin Switch's official spare hook "Stepped #10/#9" and adjusted to be almost the same length. (Please note that there may be slight variations in length due to the handmade nature of the product.) Please consider purchasing. #Tairaba #Fishing
