These lip plates were acquired from the Mursi tribe where lips plates (dhebi a tugoin) are worn by the women as a symbol of beauty. A girl’s lower lip is cut, by her mother or by another woman of her settlement, when she reaches the age of 15 or 16. The cut is held open by a wooden plug until the wound heals. It appears to be up to the individual girl to decide how far to stretch the lip, by inserting progressively larger plugs over a period of several months. Two or four lower front teeth will be removed to accommodate the lip plate and to allow the girl to speak clearly when wearing the plate. Some, but by no means all, girls persevere until their lips can take plates of 12 centimetres or more in diameter
The Mursi, Chai and Tirma are probably the last groups in Africa amongst whom it is still the norm for women to wear the large pottery or wooden discs.
