The Invisibobble Original Save It Or Waste It is a set of 3 shades of hair elastics that provide bobble- and kink-free hair. This hair elastic is specially designed to ensure that after wearing a ponytail or bun, you won't have any bumps or kinks in your hair. Because there is no iron incorporated into the elastic, this hair accessory is also healthier for your hair! Your hair is not pulled together but rather distributed so you don't have a headache at the end of the day. In addition, the elastics are water resistant and your hair will sit well all day!
