We pay more attention to our quality. We have our own quality
control who take the quality seriously. If he find the tin is not
good, the person who make it will be responsible for it. If the QC
think the quality is good. Then the sales person will check the
quality to see whether it conform to the customer's demand. If the
quality is ok, the the tin will send to our customer and he will
check the quality at last. If customer is not satisfied, we will be
responsible for it.
