This is a soft plastic grub 2 1/8" long that looks and swims like a minnow in water.  The grub has a jointed body and a vibra/paddle tail that over a double-action.  The tail wiggles and the body has a little wave action thus Double-Action.  This has been proven to catch many species of fish..CRAPPIE, Perch, and Smallmouth Bass.  Especially good for larger Crappie.  There are 10 minnows/grubs per bag.
