The invisibobble® SLIM offers an intricate touch to the famous spiral shape of the original hair tie. The unique spiral structure distributes pressure evenly on your ponytail, to ensure a strong and comfortable fit. The bobble leaves no traces in your hair, and is waterproof, designed not to snag dry or wet hair. Perfect for creating comfortable hold that stays all day, the bobble looks delicate in the hair and provides a subtler finishing touch, perfect for finer hair types.
