Headbands are super stretchy and buttery-soft. These stretchy twist headbands are perfect for anyone, anytime! I love wearing them when I don’t feel like styling my hair (you know, day 2 or 3 of dry shampoo!) I also keep one in the bathroom to hold my hair back when I was my face. Stylish and comfortable. Fabric – Stretchy Polyester Blend. Optional Buttons – 1″ in diameter securely attached to the headband, a bit behind the ear. I find this placement is best so the mask isn’t pulled up toward your eyes. Measurements – Approximately 3.5″ at widest point. 19″ in diameter which fits the average teen & adult head (if you need the headband larger or smaller, just leave a note at checkout). Care instructions – Machine washable on delicate cycle, in cold water. Lay flat to dry.
