There are two sizes, a large body of 8 inches and a 5.8 inch that was released as an additional size, and the entire body is ribbed, so when the fish eats it, it sucks in deep without discomfort. By making it into a full body rib shape, you get the strongest water bite, firm vibration, and natural action.
The original S.A.F material attracts fish with smell and taste and brings a long bite.
* S.A.F is an acronym for salt (SALT) + amino acid (Amino) + flavor (Flavor)
