AGE-OLD PRACTICE. Tboli women of Lake Sebu, South Cotabato in Mindanao, are not satisfied with one earring in each ear. The more earrings, the better. Thus their ears are pierced not only on the lobes but also along the outer rim. The women, young or old, have a choice of earrings: kawat (simple brass rings);bketot (round mirror surrounded by colored beads);nomong (chandelier type earrings made of brass links and beads);bkoku (made of triangular shells); and kowol or beklaw (combination of earring and necklace).
