Bobby pins

A bobby pin is a type of hairpin. It is a small pin or clip, usually of metal or plastic, used to hold hair in place. Typical bobby pins are plain and unobtrusively colored, but some are elaborately decorated or jeweled. A bobby pin is a double-pronged hair pin that slides into hair with the prongs open and then the flexible prongs close over the hair to hold it in place. Bobby pins became popular in the 1920s to hold the new bobbed hairstyles.

Decorated bobby pins are sometimes used to be noticed in hair. A decorated bobby pin can have beads, ribbons or other details on it and is usually worn to pull back front sections of hair while looking more decorative than a plain bobby pin.
Recently, due to their cheapness, strength and durability, bobby pins have been applied for a variety of different uses. Bobby pins can also be used to hold cloth headbands or bandannas in the hair.
To use a bobby pin, simply push hair into the desired position and push the bobby pin into place. There is no need to open the clip first.
