Holds at least 4 guitar picks and snaps onto a 5/8" diameter microphone stand. Fits snug to the mic stand and doesn't slide around. Picks slide in and out easy enough where you wouldn't pull the holder off the stand but tight enough where they wont fall out. 4 inches long. I printed one out and gave it to my uncle who is a musician and he loves it and said it looks and functions just as good as ones that sell in store
