Mr. Zhou called Aoqun Xiaowu and said that the quality of the flexible test tube brush provided by his existing supplier was not stable. Now he is looking for a manufacturer with a guaranteed quality and asks Xiaowu to visit him to discuss cooperation matters.

The next morning, Xiao Wu brought a model to visit Mr. Zhou, and introduced him the flexible test tube brush produced by Aoqun in detail. This product is made of pure nylon with a rebound rate of up to 99.9%. The new PA is rubbed at a speed of 1 million times without deformation, thereby eliminating bending and filament loss. It has the characteristics of aging resistance. At the same time, Xiao Wu tested Mr. Zhou ’s original supplier ’s brush sample, the pull force is less than 3KG, which is prone to filament loss. Later, Xiao Wu left the model for Mr. Zhou to test.

Ten days later, Mr. Zhou called Xiaowu and said, "The flexible test tube brush samples provided by your company have been tested by the technical department and there are no bends or filament loss. The quality is really guaranteed. The products produced by Aoqun are really good.
