Hair Comb (Kanzashi)
Kanzashi （かんざし）is hair ornaments used in traditional Japanese hairstyles to hold a person's hair in place in a hair bun or similar hairstyle, securing the most artfully arranged hairstyles. Many hairstyles are not possible without it` so they still have a great importance.
It was rather used as good luck charm than an ornamental hair pin at the beginning. Height 4”(10cm), Width 2.5”(6.5cm), Thickness 2.1mm.
