This Kanzashi Flower Hair Clip is approximately 1.5" in diameter and is on a fully lined double prong clip. It also is reinforced with non slip on the inside of the clip to assure placement and it will not fall out of your daughters hair. This could also adorn any stretchy head band to give it a little kick. Again with the non-slip I have it will stay in place wear ever you may slide it into or on.
