The lip plates of Mursi Women
A new sect of people from Europe and other parts of the world who pierce their lips and other parts of their boy in aspiration to be like some tribes in the wilderness of Africa and increased sexual stimulation are coming in to the scene. Apart from this new trend in the modern society, there are very few groups of societies in the world whose women wear labial and lobular plates. The Mursi and the Surma, who live in the lower Omo valley region of Ethiopia, are the most typical ones.
The plates, made from red or black mud or wood, are produced into different sizes by the Mursi/Surma women themselves. The shape varies from circular to trapezoidal, some of them being hollow-centered, and with decorative incisions. .
