From "Bonze" Fleet on the DLB:
"Just as the name suggests DLB is one "Deadly Little Bullet". With a full lead insert the DLB runs with a nice black water ripple which proves deadly! This is one lure that will catch anything that swims and keep you in the meat all day! Skirted Length: 320mm / 12.5” Hook Size: 9/0 – 10/0 Leader Size: 300lb – 400lb."
This particular head is from their "Custom" lineup with a charcoal rainbow-iridescent fish scaled wrap covering the insert with a set of red eyes.
