Review title is cute [SEP] i have long, very thick hair as all my daughters do too and we like to keep our hair up most of the time.  I have many many clips and most of them are not good.  I always break the spring in the clip or one of the teeth.  These are metal and a cute design and not too heavy.  They grab the hair and then they really don't move.  No sliding down, or shifting around,.  They are easy to grip, open and place in the hair.  They do open nice and wide too. What i like is that the teeth meet under the hair.  when you have thick hair, sometimes the clips don't close around the hair tightly becuase the spring is too weak.  this has a nice strong spring so it snaps back closed and around the hair and holds it in place.
