Pelagic fish hooks typically have thick shafts, which may not be suitable for the line size. The hook exclusively designed for slow pitch jerks for pelagic fish is called “SEIGI,” which was developed based on the insights of top angler Yasuo Nishimoto.

The hooks are entrusted to “Hariyoshi Co., Ltd.,” which has a long history in Hyogo Japan and specializes in hand-bending small hooks, ensuring consistent production. Moreover, these hooks were developed exclusively for STUDIO Ocean Mark.

The silver-plated finish, which suppresses unnecessary light, also boasts outstanding corrosion resistance.
