Dear customer, thank you very much for choosing Solarbio. You can't use the goods in time because the freight forwarder you recommended takes a relatively slow delivery time. Previously, after you placed an order, we arranged production and transportation without any delay. I also shared COA and datasheet for you. If you have any questions, please feel free to contact us for further verification. We attach great importance to your experience and hope to have the opportunity to provide you with better service!
