Large Barrette:
This is great for thick hair or a lot of hair. The barrette is 3 inches long.
Medium Barrette:

This works well with children who have thick hair, but may not have a lot of it. This barrette measures 2 inches long.
Clip:
In this clip the flower sits at an angle, which is good for in front of a ponytail. It also can be attached easily to a headband, and holds great if simply slid into hair.
Alligator:
This can go in a child's hair, but works best on a headband as it is heavier than a snap.
Snap:
This is a non-slip clip that can work well for all age groups. It especially works well in children with very little hair, such as infants.
