Remember the post I did on the FHI T-Rex Clips? Shortly after I put the post up, I headed to the local Sally Beauty Supply in search of them and encountered this less expensive version. There's 4 in a pack, 2 large and 2 small ones, and I got them for $4.99 with my Sally Beauty Card.
I really like them. They grip and secure the hair very well. Perfecto. Just be careful taking them out. The only con I experienced, with one of them, is if I wasn't careful taking it out of my hair some of my coils would get caught in the one metal part under the top part of the clip. This only happened with one of them in the pack (and hopefully none in your pack will do this) so just be gentle, like you should already be with your tresses. :D
Give them a try. You might not look at the usual plastic hair clips for sectioning hair the same way. ;D
