This holder is both convenient and unobtrusive.  I've bought half a dozen now, and I've got them on each of my guitars.  It stays conveniently out of the way above the nut, is easy to install and remove on a minutes notice. It holds both itself and two picks securely, yet the picks are easy to grab on the fly.  It's one of those simple but effective little gizmos that you'll kick yourself for not dreaming up first!
