Storm Koika Metal Jig Lure 60g Proving a big hit, the Storm Koika Jig Lure is a smart option this season. The Storm brand continues to deliver quality and value. Check it out today! Koika is the Japanese word for cuttlefish, a common prey of many predatory fish. Specially designed for slow-pitch style jigging, Koika jigs have a centre-balanced, broad profile that allows the jig to flutter enticingly on the fall. The dense and compact body design of the Koika enables it to easily travel through the depths, allowing you to quickly reach deeper water to where the fish are holding. Give it some slack line on the drop and the Koika will flutter and rock as it falls.
