Barter is the present and the future of international trade, especially for people who is starting in the import export business. Barter and more: Triangular operations.
I recently received an email from Avy of Germany saying that I need a test tube brush to clean my test tubes. The cleaning effect of the test tube brush use in chemistry purchased from another supplier last time was not satisfactory, because the test tube diameter and length were different, and the length of the test tube brush did not match the test tube. Avy asked if we could customize test tube brush use in chemistry with different lengths.
Three days later, Avy received the test tube brush use in chemistry sample and arranged the test for the first time. The test results were very satisfactory to her. Avy called Roger and said: I want to place an order for 10,000 sets for you. I will cooperate with you for a long time and refer the customer to Aoqun.
