Things get wild with this bait! The ultimate whirlwinds for the trout lake. This will also lure lazy fish out of the reserve. The Iron Trout Swirly bait runs on a fixed axle, to which a swivel is already attached on the hooking side to avoid line twist. The Iron Trout Swirly Loop is made of zinc material and therefore poses no danger to the environment. Weight: 2.8 g.
