The True Bass True Lock Underspin Jig Heads offer a unique combination of performance and flash. With a premium willow blade attached by a high-quality ball bearing swivel, these jig heads provide constant and fluid blade rotation that translates into bright flashes of light and enhanced vibration. This added feature helps to trigger more bites from fish. The keeled head shape and perfectly angled line-tie also help maintain a horizontally balanced posture at any retrieve speed. This allows anglers to adjust their retrieve depending on the mood of the fish. The True Bass True Lock Underspins are designed to work seamlessly with swimbaits, providing a solid grip onto soft plastics without the need for glue. Fast shipping ensures that you can get out on the water as soon as possible.Key Benefits and Features: Weight: N/A Hook Type: Mustad Ultra Point Blade Material: Willow Swivel Type: Ball Bearing
