Mr. Zhou is the purchasing manager of a glassware company in Zhongshan. Some time ago, he called Aoqun’s salesman Wu, saying that the quality of the instrument brushes and sterile processing provided by his existing supplier was not stable. After using it for a period of time, the customer found that there were bending with filament loss, etc. A guaranteed manufacturer cooperated and asked Wu to visit the model to discuss cooperation matters.

The next morning, Xiao Wu took a sample to visit Mr. Zhou and introduced him to the instrument brushes and sterile processing produced by Aoqun. The product is made of pure nylon wool, the rebound rate is up to 99.9% as it is new PA, high-speed friction for 1 million times cannot deform the brush, thus eliminating the phenomenon of bending and falling filament; it has the characteristics of anti-aging; meanwhile, Wu tested it on the spot. Mr. Zhou's original supplier's product, the pulling force is less than 3KG, which is prone to filament loss. Subsequently, Xiao Wu left a sample for Mr. Zhou to test.

Ten days later, Mr. Zhou called Wu and said: "The sample of the instrument brushes and sterile processing provided by your company has not been bent or fluffed by the technical department. The quality is guaranteed, and the production is really good." Mr. Zhou has placed 20,000 orders.
