Fluorescent red needle head are typically baiting tool used in surfcasting or carp fishing - they help anglers thread worms or other soft baits onto the hook or rig without damaging them. The "essence" part is likely marketing language, suggesting precision or ease of use rather than an actual liquid essence.
To make it clearer:
Needle heads: Long, thin baiting needles designed to pierce and guide worms or soft bait.
Fluorescent Red: The bright color makes them easy to spot in low light or among tackle.
Threading worms: Instead of tearing the bait, the needle slides through smoothly, keeping the worm intact for better presentation.
"Essence" phrasing: More poetic than technical - it implies effortless baiting rather than a literal essence.
