About the Brand:

Invisibobble was created by the blending of the words invisible' and bobble'. The magic trick to invisbobble's lies in its peculiar telephone cord shape. When this hair ring is wrapped around the hair, it places uneven pressure around the circumference of the ponytail; standard hair rings put even pressure on the hair, leaving an obvious mark.
