Mr. Huang is a manufacturer of various flasks and needs to use a large amount of 2000ml round bottom flask brush. The previously purchased 2000ml round bottom flask brush often has filament loss problems, but the feedback has not been resolved many times. Mr. Huang decided to change to a more professional brush factory.

After listening to the introduction of his peers, Mr. Huang contacted Aoqun and learned that Mr. Huang needed to find a 2000ml round bottom flask brush that could not lose filament. Mr. Li told Mr. Huang: "Most filament loss in 2000ml round bottom flask brush is mostly due to a bad production process, and there is no tightening and insufficient pulling force. Aoqun is a high-tech company specializing in the production of 2000ml round bottom flask brush. The company has many specialties, and the products are all produced by German fully automated brush equipment to ensure that the 2000ml round bottom flask brush is well formed. Before the product is shipped, we will carry out a test to really achieve reliable quality." Mr. Li sent a 2000ml round bottom flask brush sample to Mr. Huang for comparison for the first time.

Three days later, Mr. Huang formally placed an order for 10,000 2000ml round bottom flask brushes, and affirmed the samples of Aoqun. Mr. Huang's feedback: "I always thought that the flask brush is a product with no technical content. After listening to the detailed introduction of Aoqun, I learned that the flask brush also has a lot of technical content, so I chose to professionally 2000ml round bottom flask brush manufacturer, AOQUN."
