The hairpin, or hair-slide, is a decorative item used by women to hold their hair in place. It consists of a flat base made of metal, plastic or other material and often decorated with gems or intricate patterns. The end of the base is typically shaped into an arch which holds the hair in place. Hairpins are available in various shapes and sizes and can be worn alone or as part of a hairstyle.
