I am always losing picks or even worse people pick them up and don't return them. It's hard to know who swiped a pick when everyone has Fender or Dunlop picks but with the art of the masters on the picks, I'll know exactly borrowed a pick! The picks are well made and the great renaissance art images are inspiring! Picks test out great on a martin acoustic, great divide acoustic, seagull 12 string, fender acoustic bass and a ukulele. My niece plays the ukulele and is notorious for losing pics. This would be a great gift for her! Not only are there lots of picks but she can broaden her art education!
