These blanks are quality made with the internal weight transfer system included. Sealed with KBS Diamond Clear and dressed with Bill Lewis Set-Lok needle point #4 trebles, they're made to attract fish and get them to bite. These are custom patterns you just can't get anywhere but right here at JBCo. Each blank batch is random tested and tuned if necessary, so you can be confident you're getting a quality bait every time. They weigh 3/8 ounce and dive 4-7 feet.
