Best Seller. Formerly named Riverge Grand Max, Seaguar fluorocarbons feature a unique, multi-dimensional, polymer structure that gives class leading knot strength.  To gain maximum performance always lubricate any knots before tightening.  Made in Japan.

This is one of the strongest fluorocarbons available.  It is practically invisible in water, and sink readily without treatment at about 3 times the speed of nylon.
