These U Shape Hair Pins are just what you need to hold your hair bun in place. Whether you want hair bun pins for an every day hair bun, or perhaps for a special occasion, or for a ballet bun - you need these hairpins in your life to keep your bun looking immaculate. Suitable for women and older girls, or for men who wear their hair in a bun, these hairdressing accessories are essential hair clips to keep at home and in your handbag to keep your hair looking great throughout the day.
