Being using their product for long time ,delivery take more then a week .Thank to Qxpress for their speedy service .But one of the order went wrong as I order White Chrysanthemum powder Serum, but received sun screen cream .Now i have to send the incorrect item to korea for exchange ,dont know when i can receive my powder serum 😱 horrible service. Be careful when you make your purchase ,Big mistake for choosing this seller. PS WRONG ITEM FINALLY REACHED S KOREA ,THEN SELLER TELL ME THEY DONT HAVE STOCK TO GIVE ME AND ASK ME TO GO FOR REFUND OR EXCHANGE !!! What a service 😱😱😱😱
