INVIZ-WIRE- Tandem Thunder Willow- INVIZ Wire Spinnerbait- Features a heat treated brown colored super wire which is stronger than traditional stainless wires and is much less visible to fish.The stealthy, natural appearance draws attention to the skirt and blades without the distraction of wire flash which is especially important in clear water.The .028 wire collapses easily to assure greater hooks ups but also provides a very strong vibration due to its resiliency.
