From "Bonze" Fleet on the D Shackle:
"The D Shackle may only be a small lure but with its large cup face and reverse tapper you would think you are watching a much larger lure. This lure is perfect to run behind your dredge in a spread of small lures or on the rigger in a spread of larger lures. A very easy to use lure that is in my starting line up everyday! Skirted Length: 270mm / 10.5” Hook Size: 8/0 -9/0 Leader Size: 200lb – 400lb."
This particular head is from their "Custom" lineup with a clear resin pour and a yellow abalone shell covering the insert. Skirted in black with holographic glitter and a red lateral line over yellow/white/black with holographic glitter.
