4" Mammy Jammy Improved! $3.50 These 5 packs are serious business, not for the faint at heart. Big fish eat big bait and these fit the bill. Throw in combination with a 1/2 or 3/4 ounce jig and big bass will thump'em. We have updated the shape for an easier to trim head and improved dimples to grab bubbles and slip through weeds better.
