Dear ***
I'm terriblely sorry that such kind of mistakes came forth.It was so busy the day we mail sample that our clerk posted the sample before the quality department had checked it.we think that there's no big problem since only six samples was unqualified.It is kind of because of the weakeness of our administration.our factory director attach great importance to this affair.he demanded that this kind of affair never happen again and no matter how busy we are ,how many goods we manufactue ,it's necessary that we do according to the produce regulation.we guarantee this kind of situation will never happen again when we ship on due form .Thank you .
