Special pin-like stud with a big hat is used to decorate the lower lip piercing, it's called labrets or labret. In the Indian tribes living in the Amazon, the men gradually stretch the piercing of the lower lip as long as there will not be able to accommodate a large wooden disc. In some areas of Africa, local residents as well do "lip hard drive," which women express their subordination to their husbands. Eskimos used for labrets bone, and thus mimic the walrus during a hunt in an attempt to calm the "Spirit of the Walrus." In the pro-Spanish Mexico, only Aztec warriors, holding a high position in society allowed to wear Teshey, "stone lips" or labrets made from semiprecious stone. Tentetl for the ruler was made of gold in the form of an eagle.
