Isevisi esingayinikeza
1) Inkontileka esemthethweni ingasayinwa
2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa
3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa
Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
Singabakhiqizi, imboni yethu itholakala eShandong, kodwa futhi singakunikeza insizakalo eyodwa yokuthenga!
T/T(i-telex transfer), Western Union, MoneyGram, BTC(bitcoin), njll.
≤25kg: zingakapheli izinsuku ezintathu zokusebenza ngemuva kokutholwa kwenkokhelo. ＞25kg: isonto elilodwa
Iyatholakala, singanikeza amasampula amancane mahhala ngenjongo yokuhlola ikhwalithi!
1kg isikhwama ngasinye fpr amasampula, 25kg noma 50kg sigubhu ngamunye, noma njengoba ubufuna.
Gcina isitsha sivalwe ngokuqinile endaweni eyomile, epholile futhi enomoya omuhle.
