Dynamite Baits Tigernut Hard Hook Bait is a carp fishing hookbait made with a recipe that keeps the nutritional goodness of a boilie while offering a 48-hour breakdown time, rather than simply being dried to achieve hardness. The baits can be hair rigged with a standard baiting needle, with no need for a bait drill, so they stay in prime condition when carp arrive. Available in two sizes: 14/15mm or 20mm.
