The "Crazy Flapper" is dual injected using different types of PVC plastics. This gives the "Flapper" the perfect combination of softness and durability. The secret to its effectiveness is the "Crazy Flapper's" patent pending design. Its body design slithers through cover while the claws and tentacles flutter seductively following the slightest movement. This allows the angler to use less weight, slow down the fall and keep the bait in the strike zone longer.
