This is a pack of 3 standard model felt picks by D'Addario. They are the same shape as and a little larger in size than a standard 351 pick and have a cutout to help with your grip and allow the pick to pivot between your fingers since 3 mm thick felt does not flex. They are perfect for ukelele, autoharp, guitar, bass, etc., anywhere you might want a softer attack on the strings like if you were just using your thumb.
