Invisibobble Nano Pretzel Brown
The magic trick to invisibobble's traceless outcome 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 uneven pressure produced by the invisibobble allows for the hair to be held strongly in the ponytail without being too tight. This gives individual hairs more space within the ponytail than they would have when wearing a normal hair band.
