These are Tai Rubber (Tai-Raba) jig heads. I received these from a friend, but I don't use them, so I'm selling them. I don't know the manufacturer or specific type, but I was told they contain tungsten. My friend also recommended them for Amadai (Japanese tilefish) fishing. 60g 80g x 2 120g x 3 130g 150g x 2 Total: 9 pieces Also, as a bonus, I'll include a new Start tie hook set (new). It includes the new Magic Curl Curly and a straight tie.
