I have used these for a photo shoot where I did a bunch of little girls' hair and makeup. Large bobby pins are so hard to maneuver around the fineness of little girls hair, so one of the mothers brought me a pack of these! Instantly fell in love. They're the perfect size and actually hold fine hair for a decent amount of time... As long as you use them correctly. Once you have one bobby pin in place, take the second, open it with ridge side face up and over lap and lock it into place over the previous bobby pin. That will create and X and make them stay longer. I also like how they come in a range of colors to match hair color so they're less noticeable. They're easy to remove and have no pull on the hair!
