This material has been developed to guarantee attractivity and a high quality of swimming motion, even at low speeds.
The phtalate-free PVC is extremely soft and has been injected with powdered shrimp in the lower section, with salt to optimise its balancing.
A fish oil-based attractant maximises the efficacy of this soft lure.
If you only use them very occasionally, take apart the sinker heads, as the presence f salt may damage them.
