The Keitech Super Round Tungsten Jig Heads are high performance, professional-grade jig heads from Japan. The popular round head with a slender collar won’t tear your worms and keeps your soft plastic baits secure. The hooks are designed with a certain bend, which increases strength and hook ups. Tungsten is significantly harder and denser than lead, which enables the rounded head to be smaller. Keitech also allows you to choose the hook size and the weight of each jig head.
