Purchased to be able to keep a few toothpicks handy and readily available. I have a small gap between two of my back teeth and EVERY time I eat food gets stuck. I wanted something to keep some toothpicks clean and protected from breaking so I have them accessible when I am out. I keep this in my purse rather than on my keychain so I can't personally comment on having them on your keychain but so far I am happy with this product to keep handy in one of my small pockets in my purse.
