I have a lot of hairpins, so it's fun to wear them on different days! Short hairpins are recommended for holding bangs in place. They look cute when worn with two side by side. My elementary school child also uses them. They can also be used to hold bangs back when washing your face or applying makeup. Some have weight to them. Since they are resin, please refrain from purchasing if you are sensitive to smells. Long hairpins: Approximately 8 cm long Short hairpins: Approximately 5 cm long
