Mr. Li is the boss of a small commodity trading company and often helps foreign customers buy products on their behalf. In the last six months, the surgical brush price products purchased by foreign customers are very bad. After a period of customer use, the whole brush will show serious fork hair and can no longer be used. Customers are very dissatisfied.

Through the search, Mr. Li found Mr. AOQUN, and Mr. Li heard Mr. Li's confusion, when he told Mr. Li:``AOQUN's flask test tube brush products were made of pure nylon wool, with a rebound rate of 99.9%, high-speed friction for 1 million times without deformation and no hair loss;Good aging resistance, no bending, can keep the performance intact under different environments, and the test tube applied with good tensile force produced by the group is good. The tensile force of every 5 hair wires is more than 3Kg, which greatly reduces the frequency of frequent replacement of the customer and saves the cost for the customer. ``Mr. Chestnut then offered a sample to Mr. Li.

Ten days later, Mr. Li called Mr. Li and said, "the sample of surgical brush price provided by your company has been confirmed by customer testing. Through the use of the experiment, the elasticity is very good, and there is no more bending, hair loss and other phenomena, which proves that the quality is really guaranteed." On the same day, Mr. Li placed an order for 3000 surgical brush price.
