I have been ordering from this supplier and in general had good comunication and was happy with the product but I rush ordered 100 bags and i have had customers sending the bags back because the zipper keeps breaking or bags keep tearing 3 days to 2 months after i sell the bags so far i am up to 20 bags returned. i have lots of email and picture proof andthey have nade no effort to cover my loss telling me they will give me bags if i order more.
