The GOSEN Don Pepe ACS (Accentuated colour system) 4 ply braid was designed to cast very light lures around when the fish are being fussy. The line is made from Toyobo fibres from the Izanas company in Japan. The Toyobo fibres are stronger than any other braid on the market. Don Pepe is the most popular GOSEN braid being sold in Japan. The Accentuated Colour System (ACS) holds it colour for longer and helps you see where your lure lands.
