Owner Twist Lock Light. Listing for 3/0, 4/0, and 5/0 sizes. Only one 4/0 hook has been used, so there are 4 4/0 hooks remaining. They are unused. The remaining 3/0 and 5/0 hooks are all unused, with 5 hooks in each size. Product Description: Based on the basic concept of using stick-type soft baits, the wire diameter has been made lighter and the gap narrower compared to the original. This is an American import model highly praised by Gary Yamamoto.
