Selling 20 inches, about 60centimetar of dark brown hair

Hi everyone , I was growing this hair with a special care for 4 years now and I am ready for the haircut. I have a strong, healthy hair and I am looking to sell ASAP. I will sell only 20 inches (or 50-55 centimeters), so please do not reach if you want the whole hair. I already had so many offers to go bald for a great amount of money and I did not accept, I am offering 60 centimeters only.
