Key chains are great for organising keys, use them for luggage tags so you will never pick up the wrong suitcase in baggage claim again. Choose a unique design that you can easily identify, and add your contact information so you know your luggage is yours for sure. Use key chains to decorate more than just your keys. Use key chains to decorate your backpack, or purse. Attach your key chains to the zipper pull of your purse or backpack to add some character as well as to make the zipper pull easier to grasp. You can use key chains to hold flash drives if you have multiple flash drives that you use to transport school papers, important work documents or your pictures.
