WCB Hookbait Boilies are available in an 8oz jar and contain two sizes, 16mm & 20mm. They are made from high quality ingredients, including grains. Proven as “Trophy Size” catchers thanks to their double strength flavor formula. Steamed to lock in the flavor, our Hookbait Boilies slowly release the perfect amount of flavor to get carp on the bait. The newest formula makes our Hookbait Boilies even brighter, more visible and better balanced for perfect presentation in the water.
