“Jr. Seaguar” is an affordable fluorocarbon fishing line provided by Kureha, the first company in the world to produce fishing line made of fluorocarbon (vinylidene fluoride). It has extremely low water absorption, so it maintains its strength even after long-term use. In addition, its refractive index is close to that of water, making it transparent as if it were dissolved in water, making the line difficult to see underwater. It also has the strength to withstand sudden fish pulls, rubbing, and root slippage (when the line touches obstacles such as rocks), and the flexibility to make it easy to handle, and is suitable for large fish such as black porgy (chinu), sea bass, mejina (gre), and red sea bream. We have a lineup of 7 handles from No. 1 to No. 5 that can be used for various fishing tackles such as embankment fishing and reef fishing.
