The Dartspin 4.5 Round Jig Head is a version of the Dartspin mounted on a round zinc jig head with an exposed hook. Available in 8 and 12 grams, we recommend it for all straight fishing techniques or for fishing with a few pulls in search of pike, perch, zander or sea bass. The material used is a thermoplastic elastomer which can react when in contact with other types of soft plastic, so we strongly advise you to keep them in their original packaging or in a box (stored horizontally) where you wont mix them with other soft lures.
