Graduation Gifts for Girls

What do you give girls graduation from high school?
I love to give gifts that will actually be useful at some point. A couple years ago I made bags with some tools in them. So, this year I was in charge of getting a gift for the 8 girls graduation from high school. Honestly, what girl thinks about needing a hammer or screwdriver until you actually need it---right that minute? So, I think it's a perfect gift.
