The Invisibobble has various advantages to it:- It is traceless- Avoids headaches.- It is caring to the hair.- Wearable with all hair types.- Bracelet feature.Traceless: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 hairband.Caring:The Invisibobble offers more than just a traceless outcome. They are also known for being caring to the hair. The seal is not made of metal, which is often the cause of breaking hairs. Instead, it is made by soldering the two ends together smoothly, so that they don’t get caught in the hair nor do any damage to it.All hair types:An Invisibobble can be worn with any hair type No matter if curly, straight, thick, or thin, Invisibobble is always wearable.Pack of three.
