Ukuthengiswa ngokuthe ngqo kwefektri, iibhola zemagneti.Inzuzo yethu yemveliso:
1. Xa kuthelekiswa nomnye umthengisi osebenzisa i-N35 grade ekrwada, umzi-mveliso wethu usebenzisa i-N38 grade ukuqinisekisa eyona magnetism inamandla.
2. Imigangatho emihlanu yepeyinti yepeyinti ye-nano ukuqinisekisa umphezulu womelele ngakumbi ukuba abantwana badlale.
3. Sinobubanzi obuhlukeneyo kunye nemibala yebhola, ububanzi be-3mm kunye ne-5mm bubukhulu obuqhelekileyo, senza ngokwezifiso i-diameter eyahlukileyo ngolu hlobo lwebhola yemagnethi.
