These copper barrettes are a redesign of the leather and wood barrettes that some of us remember from the '70s. Finishes may vary. Depending on the thickness of your hair, you can use the smaller one to pull your hair back and the larger one to put your hair up. The barrettes may be adjusted to allow for more or less hair to be held. However, do not make large adjustments or repeated adjustments as the metal may eventually stress. The stick needs to be able to go through both holes. The smaller barrettes can also be used as scarf pins and really add pizzazz to an outfit.
