Thank you for viewing! This is a set of 200 black, knotless hair ties. Perfect for children in junior high and elementary school who can only use black, as well as adults who want to tie up their hair. These are classic black hair ties, perfect for everyday use. Approximately 4.5cm in diameter. Ideal for work, school, and sports. Made with a material that is gentle on the hair and less likely to tangle. Comes with multiple ties, making it convenient for stocking up! It's reassuring to have one in your bag or pouch. They are a bit thick and stretch well, so you can use them repeatedly.
