A musician isn't dressed without a pencil!
There's nothing more embarrassing than having to root around the floor looking for your pencil after it rolls of the stand -- especially while the conductor is waiting. The Pencil Clip attaches to the Hamilton KB400N or KB600N stand and keeps your pencil handy for quick notes and changes.
Don't keep the conductor waiting! (They hate that.) Keep your pencil handy and off the floor!
