Set of 7 guitar picks in a metal tin.
Ideal for guitarists.
If you don't play guitar, simply leave these laying around the flat to impress members of the opposite sex. Certainly cheaper than buying a guitar and learning to play the thing. Tell visitors you have these because you actually are a member of TISM! (though that's likely to see interest in you from the opposite sex diminish rapidly.)
Singers can use the tin for those times when they need to visit the powder room.
Not much use for drummers.
