Simply put it on the head part of the BinBin Switch to easily increase the volume and appeal, and it is extremely effective against highly active red sea bream and rock fish. Adopts an "elastomer material" that has a softness that creates a "raw feeling" and a high strength that is difficult to break even with a strong bite. Contains "squid flavor" that strongly stimulates fish's sense of smell. Please close the zipper tightly and store it so that it does not adhere to clothing.
