This Fishing Line Leader is a titanium wire that is very elastic, kink-resistant, and corrosion-proof. It can quickly sink in the water which allows the angler to get down deep using a short length of the line. It can easily curl back up without any hassle. At the same time, this wire can quickly spool onto reels. You can also achieve a better bait presentation that can attract the fish underwater with the help of this wire. Always remember that using a reliable leader wire is very important. =
