FEWER HEADACHES - TELETIES holds hair firmly in place with less pulling and tightening. Their firm yet flexible form provides greater hair support, reducing head and scalp tension. REDUCES DAMAGE and CREASES - TELETIES spiral form and smooth surface mean less direct contact with your hair for an easier, smoother removal and leave less of a crease compared to traditional ties. WATER RESISTANT - TELETIES are water resistant, so you can get them wet without worry. And since they won't retain water, you'll never have to deal with a drippy hair tie again. SIZES - Tiny: For kids and tight braids. Small: For thin to medium thick hair. Large: For thick to super thick hair.
