Delrin, created by DuPont, is strong, resilient and extremely durable. These picks are die cut and tumbled for a smooth, rounded edge resistant to chipping. The matte finish improves grip, even after hours of playing. Often called the Fender pick, the 351 shape is the pick most associated with Fender. A wider body and a rounded tip have made this pick a favorite with players of every style.
