These are very buoyant, durable, air ball pop ups made with Pro-Stim Liver Base Mix to ensure they colour and aroma-match our Pro-Stim Liver boilies and other products in our successful Pro-Stim Liver Range. They have a tough, nuisance fish-proof skin but are pliable enough to be trimmed to achieve the desired buoyancy for optimum rig performance. Available in 12mm, 15mm & 18mm size.
