Mr. Zhang, from Hong Kong, said: Recently, customers have complained that the wine glass sponge brush has lost filament during the process of cleaning the bottle. Wine glass sponge brush has been said to be a bad product. He asked us to solve this problem.

Mr. Zhang is using a wine glass sponge brush with a cotton head for the customer, and the cotton thread is easily broken due to long time using. Later, we called Mr. Zhang to take a video of the bottle and saw it was a commonly used bottle. According to the size of the bottle provided by Mr. Zhang, we selected a 0.2mm diameter transparent nylon instead of the cotton thread, and sent the sample to Mr. Zhang within 2 days.

7 days after the sample sent, we received another call from Mr. Zhang. After repeated tests, this wine glass sponge brush that made of nylon will not lose filament, and really help them to solve the problem of filament loss. At the same time, the nylon resilience is particularly good, and the market response is very good. Mr. Zhang place us an order of 8,000 pcs.
