Extra heavy guitar pick from Fender Dura-Tone series. This durable pick is crafted from extruded Delrin, in black color, with a matte finish for improved grip. Long-lasting and durable, Delrin has a stiffer feel than celluloid, which gives a strong, well-defined attack to every stroke. The 351 shape—our most popular—works well for any musical genre and has a traditional feel.
