Open cell, super buoyant foam. Small pieces can be cut off and trimmed to use on Zig Rigs or for balancing hooks and baits, making pop-ups, etc. Perhaps this foams most popular application is the balancing of dead baits when pike or catfishing. Simply adding a piece of red pop-up foam adds both buoyancy (to assist presentation) and colour that stimulates the pikes predatory instincts. Many knowledgeable European surf anglers are using small 1cm pieces to add buoyancy and natural movement to their baits, calling this the ‘Hunter Rig’. 50cm (20″) length per pack. White Pop–Up foam is available in 2 sizes: 6mm or 10mm diameters. Coloured Pop-Up foam (Red, Yellow or Black) is available in 6mm only.
