Pepa parahi
Whakataki Hua
Pepa Parahi i runga i te parahi electrolytic, zinc me nga huānga tohu hei rauemi mata, na roto i te tukatuka ma te ingot, te hurihuri wera, te hurihuri makariri, te maimoatanga wera, te horoi o te mata, te tapahi, te whakaoti, katahi ka kikii. Ko te mahinga o nga mea hanga, te kirihou, nga ahuatanga miihini, te aukati waikura, te mahi me te tine pai. Kua whakamahia nuitia i roto i te hiko, te miihini, te whakawhitiwhiti korero, te taputapu, te whakapaipai me etahi atu ahumahi
