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.
The Invisibobble is composed of polyurethane, better known as artificial resin. Polyurethane is particularly hygienic since it neither absorbs dirt nor bacteria and has a very easy cleaned surface.
