Tele masani o le uaea uʻamea nikel:

Matou te tuʻuina atu oloa i foliga o uaea, uaea mafolafola, ma fasi pepa. E mafai foʻi ona matou faia ni mea e faʻapitoa mo oe e tusa ai ma talosaga a tagata faʻaoga.

Uaea pupula ma paʻepaʻe–0.025mm~3mm

Uaea fa'asusu: 1.8mm ~ 10mm

Uaea fa'a'okesaita: 0.6mm ~ 10mm
