This is a "Roly-Poly Jig" with lead weights set on the ventral side and a hollow dorsal side. It achieves a stable underwater posture with a low center of gravity and a falling vibration action that suppresses unintentional rotation. Its slim shape has low air resistance, extending casting distance. It is effective for offshore dorado and bonito, as well as casting games on surf and breakwaters. It also includes Hokkaido-limited colors that are conscious of Hokkaido baitfish such as shiwikanago, which are gaining attention for targeting sea trout and cherry salmon. #Lure #FishingGear Thank you for looking.
