These are done on Mustad Hooks and they come 2 to a pack. I have these available in 4/0, 6/0 and 8/0 Hooks. The 4/0 hooks are available in weights 3/16, 1/4, 3/8 and 1/2 oz. The 6/0 and 8/0 Hooks are available in weights 3/16, 1/4, 3/8, 1/2, 3/4 and 1 oz. With the weight being forward on these swim bait hooks, it give your swim bait a more natural side to side swimming motion. Stop reeling and this thing instantly nose dives. Start reeling again and this little jewel starts tracking just like a spinner bait. One of the best if not the best Swim Bait and Under Spin Swim Bait Hooks out on the market.
