I'm selling this because I accidentally bought it. It's new and unopened. Polyweb coating is a hybrid polymer applied precisely and accurately to the wound strings of a guitar. It provides a sound quality similar to that of regular strings after they've been played for a while, and a very smooth feel that reduces unpleasant finger noise.
