These picks are nylon, so each one will last you a couple of years (as long as you don't lose them!!) this is thicker than the .60mm, so you can dig into the strings a little better, but still a hair flimsier than the Snarling Dogs .73mm picks (I know, they're the same size, but trust me these are "flimsier"), and the grip is ok. You can't go wrong here.
