Consider these two factors:
- Guitar picks: You never think you will need one but then someone hands you a guitar and you start frenetically looking for a pick in your pockets and there is none because you didn't think of bringing one when you left your house, or you lost it in the most random place.
- Your car keys: You probably have them in your left pocket and you touch that pocket multiple times a day to make sure they are still there because you will really have a problem if you lose them.
Now, consider attaching a guitar pick to your car keys.
That is what I did. Now I always have an extra pick with me when I need it.
And as a bonus, it looks really cool.
There is one small issue I have with it:
It cannot hold many picks. Only one or two. If you try fitting more than two picks, it will be tight.
But you probably don't need more than 2 guitar picks on your car keys, do you?
Also, If you are seriously spending your time here, reading a review on a key chain guitar pick holder, you should really consider using this time to practice. Buy this thing already and go practice. You won't get good at writing riffs by reading gear reviews.
