Smelly Jelly Scents are among the most popular fish attractants on the market today. Smelly Jelly has taken the essence of each forage species and concentrated it before mixing it in a jelly base. The jelly will stick to whatever you apply it to and stay there longer. The Crab Feast was designed specifically for anglers who spend a lot of time on the water. You can use Smelly Jelly to mask your scent after handling lines and as an attractant to bring crab to the bait.
