If it was a hair then it was definitely Karin's if it was an umbilical then there is a chance it was Sarada's or Sasuke's. but I do believe it was a hair because an umbilical cord would not fit into that vial. I think it would. Umbilical cords dries up and decreases in size, my mom keeps our umbilical cords secured and sealed as reminders of when we were babies.
