Buttobi Natural Swim Metal Jig. Natural appeal in unexplored waters. Even though it is a metal jig that can aim for a flight distance of 100mOVER, it keeps a natural swimming posture like a sinking pen. It is possible to make an appeal that is not too violent and does not make you feel uncomfortable. The crest installed on the head plays the role of a stabilizer that stabilizes the complex water flow that occurs from the head to the back of the body. It suppresses the body's rampage and sideways falling, contributing to a more natural swimming posture. Rear center of gravity design that brings overwhelming flight distance. In addition, due to the line eye under the chin and the low specific gravity zinc material, it floats moderately during retrieval and can be used comfortably even in shallow surf. The zinc body, which has a smaller specific gravity than lead, can appeal with a large silhouette.
