Gone are the days when the hairpin that you can buy is plain and boring. With the help of technology these days, they are all fashionable now and you can even buy a special tool for a hairpin cotter pin. Imagine if you can make your own hairpin and design it yourself, it would be really convenient and so cool right? I remember using hairpin before when I was younger. I have a long hair and the only hair accessories that my Mom could afford is hairpin. Take note also that she only let me use those on special occasion, on regular days, I use rubber bands lol.
