Dynamite Baits Robin Red Hard Hookbaits 20mm are carp fishing hookbaits made with a recipe that keeps the nutritional goodness of a boilie while providing a 48-hour breakdown in the water, rather than simply being dried to achieve hardness. They can be hair rigged with a standard baiting needle, so no bait drill is required. This gives anglers confidence that when carp arrive, the hookbait will still be in prime condition. The bait is available in 14/15mm and 20mm sizes.
