This is a metal jig made in China. I purchased it from an OEM factory of a Japanese manufacturer that was selling on AliExpress. Therefore, it closely resembles a jig from a certain manufacturer. I used it in the deep waters of Enshunada, targeting blue-backed fish and rockfish. It has some surface stains because I stored it with rusty hooks attached. I removed the hooks because they didn't seem reusable. The fall speed is fast, so how about using it as a pilot jig for deep water? Weight: 400g Base color: Fluorescent color Fishing type: Jigging
