The VARIVAS Ocean Record 100LB shock leader is made of nylon and features an easy-to-pull-out design. There was 50m. 2 hiro (unit of length, approx. 6 feet) has been used. - Brand: VARIVAS - Model Name: Ocean Record - Type: Shock Leader - Strength: 100LB - Material: Nylon - Accessories: Spool - Features: Easy-to-pull-out design Purchased at a fishing tackle shop for a regular price of ¥2574. I use about 2 hiro per fishing trip. I stopped using it because it didn't match the PE line I was using. I think it's thick, so it's suitable for tuna or large pelagic fish... It's used, but I'm looking for someone who can use it. It's still usable. It comes with a belt to secure the line. The photos may be difficult to understand, but I can upload more photos.
