Cute hair bows attached to a pinch clip/alligator clip. Alligator clips are single prong metal barrette, you pinch one end open (like an alligator's mouth) then slide in the hair and release.  The two parts will close down on the hair.

The bow spans about 3 inches across and is 2.25 inches tall.  It is adhered to a teethy pinch clip. See the additional images for a picture of the back of the clip.
