Developed for all those spinnerbait and all other fishermen out there. Not only will it extend the bite surface area of your lure, but will speed up the process of attaching it to your favorite lure without all the added pieces. The eye already has a rubberized coating molded onto it, and also an added color attraction too. So there?s no need to scramble around looking for that lost tubing, or worrying about if the trailer hook flew off on your last cast.
