Sticks on your guitar, peels off, leaves no residue. Holds 7-8 picks. Keeps your guitar picks handy. If it ever gets dirty, you can reactivate it and clean it with a little water....its good as new. We use this on all our expensive guitars and it leaves no trace. Safe for guitar finishes. Very strong and durable. 3 medium yellow picks included. This is a must have for every guitar. A little pricey...but worth it! I feel comfortable putting this on my best guitars.
