Now you don"t have to change the wire every time you need a new cork. The innovative cork is changeable- when your cork tears up, simply replace it! You just pull the eyelets out of each end, slide the old cork off the wire, slide the new cork onto the wire and push the eyelets back into each end and you are ready to go! The nickel titanium wire is virtually indestructible, so now you can spend more time fishing!
