Some time ago, he called Xiao Liu of the e-commerce department of Aoqun and said that test tube brush where to buy, the quality of the food-grade test tube brush provided by his company’s existing suppliers was not very good. After using it for a period of time, he found that there was filament loss; Now I'm looking for a manufacturer with guaranteed quality to cooperate, and ask Xiao Liu to visit him with a model to discuss cooperation matters.

The next morning, Xiao Liu brought a sample to visit Mr. Ren, and introduced him to the food-grade test tube brush produced by Aoqun Company in detail. This product is made of pure nylon wool, with a rebound rate of up to 99.9%. The new PA has a tensile force greater than 72N, thus eliminating the phenomenon of easy filament loss; it has the characteristics of anti-ultraviolet and aging resistance; meanwhile, Xiao Liu tested Mr. Ren at the scene The original supplier's products found that the filament is insufficient in pulling force, which is prone to filament loss.

The quality is good. I also recognized the quality of Aoqun. test tube brush where to buy, I choose Aoqun." Then, Mr. Ren placed 20,000 orders.
