FLASHMER UNDULATING SPOONUndulating spoon with incorporated anti - twisting systemThe flashmer spoon swims by itself! When trolling or throwing/retrieving, the spoon undulates on its own, making the rainbow coating shimmer. By placing the spoon flat on the water, it will slowly descend (willow leaf descent). You won't need to "waddle" to animate the assembly, the spoon does the work for you. Once the spoon is at the bottom, grind slowly to raise the spoon and start again. The nickel - plated treble hook of the Triplebar model is dressed in a pearly white synthetic filament skirt, which varies from blue to purple. The anti - twist system is mounted with a swivel from the French brand J.B, a reference in terms of quality and solidity. The brass bead limits the friction of the swivel on the spinner. The swivel is firmly anchored in the spinner.Specifications - Weight: 20g, 30g, 40g and 60g - per unit
