Yesterday a Mexican customer placed an order for 80,000 surgical supplies including surgical kits, gowns, scalpels and gauze. This is a new friend, the customer saw our advertisement on the network, saw the product introduction and felt that the product parameters fully meet the requirements, left a message on our website to tell us the demand and contact information, we quickly get in touch with the customer, through whatsapp to understand the customer's specific ideas and requirements, and formulated a suitable product programme and the most preferential price scheme for the customer. The customer wanted to see the actual quality of the products, so we sent the customer product samples of surgical bags, surgical gowns, scalpels and gauze. After seeing the samples, the customer placed an order to buy and expressed his hope for long-term cooperation.
