Lake Biwa Shimotake Guide Produces high specific gravity worm "Heavy Poop 3.6" has arrived. The material is made with a 30% salt blend that combines the best needle retention and specific gravity, while ensuring a weight of over 0.6 oz (18 g). The design makes it easy to fall horizontally, and it can be used for a soft jerk. The deep grooves on the nail portion allow water to flow and prevent it from spinning during retrieval, reducing the stress of threading.
