Handmade jigging assist hooks. Hook size is #4/0, made with 1.2mm Kevlar line with the core removed. Length is approximately 3cm, but there may be slight variations due to being handmade. I've hooked up to yellowtail with these, and they held strong. If you're interested, I can make them in sizes 1/0 to 4/0, and adjust the assist length as well. Please understand that these are handmade. Thank you.
