Wakasagi sinker made of tungsten material. Uses tungsten, which has a high specific gravity and good sensitivity, making it compact and increasing fall speed. Contributes to faster retrieval. Equipped with a swivel to reduce line twist. Specially designed with a leader stopper on the side to attach a lower hook. Drop shape that makes bites easy to detect. In addition to 1g to 5g, 4 sizes from 6g to 10g, effective for deep water fishing and strong winds, have been added, bringing the lineup to 13 sizes. Can be used differently depending on wakasagi activity and water depth. 1g to 2.5g come in packs of 3. 3g to 5g come in packs of 2. 6g and above come in packs of 1. * For prevention of slippage, please wind the thread twice around the leader stopper. Also, thin lines may break if pulled strongly.
