Mr. Chen is a purchasing manager of a chemical glass test tube company. Some time ago, he called Aoqun senior sales Xiao Wang and asked whether Aoqun company can produce brush for flask; if so, please bring a sample to their company to discuss cooperation matters.

On the afternoon of the next day, Xiao Wang brought a sample to visit Mr. Chen and introduced him to the brush for flask: "Aoqun specializes in the production of brush for flask for more than 20 years. The products are all made of new rubber raw materials. Tensile force> 3KG, not easy to loss filament, strong recovery force and elasticity, passed the temperature and humidity test; the product is fast, uniform, neat, moderately rigid and durable, durable, widely used in chemical glass instrument test tubes, cleaning and polishing." Subsequently, Xiao Wang left a model for Mr. Chen to test.

A week later, Mr. Chen called Xiao Wang and said: "The brush for flask sample has been tested by our technical department and meets the requirements of our products. The export of Aoqun is really good, so I will cooperate with you."
