The Marukyu ShioEbiKo is a salt-processed shrimp powder designed for sea fishing, enhancing both casting distance and bait longevity. By simply sprinkling it onto sandworms or sliced mackerel, the powder firms up the bait, preventing breakage during long casts and extending its lifespan. The shrimp ingredients further boost the bait's fish-attracting power. Additionally, it can be used to preserve leftover bait. Ideal for casting fishing, it helps tighten the bait, making it perfect for long-distance casting and targeting deep waters.
