The Dartspin 5.5 Round Jig Head is a version of the Dartspin mounted on a round zinc jig head with exposed hook. Available in 10 and 14 grams, we recommend this jig for all line fishing, pulling or scratching in search of pike, perch, zander and sea bass. The material used is a thermoplastic elastomer that can react when in contact with other types of soft plastics, so we strongly advise you to keep them in their original packaging or in a box compartment (stored horizontally) where you wont mix them with other soft lures.
