Freshwater snails make up a large part of a carp’s diet so using the same process that Dynamite use to cook the hemp in the tins, the Frenzied Hemp & Snails Specimen Size are as natural as they can be with absolutely no preservatives added. Use as a hook-bait option either as singles or two on a hair. They have proved very successful for carp, chub, barbel and even tench. Ideal on tough waters.
