Tim, a customer from Germany asked us, “what are your best bottle brush for hydroflask?” After talking with Tim, we got to know that they sold the brush as a companion product to every consumer who bought the vacuum flask, but they received complaint that the brush had scratched the vacuum flask. The reason was that the filament was too hard. The customers were claimed for compensation.

We recommended a bottle brush for hydroflask of pure nylon to Tim. The filament diameter of the brush was also adjusted appropriately, so that the bottle brush for hydroflask can clean the dirt in the bottle without damaging the inner wall of the bottle. After receiving the sample of the bottle from the customer and adjusting the samples many times, we finally customized a bottle brush for hydroflask suitable for the customer's vacuum flask. This bottle brush for hydroflask is soft, not only can completely clean the inside of the bottle, but also does not scratch the inner wall of the vase.

We sent the sample with the vacuum flask together to Tim. After repeated tests, Tim decided to purchase 1000pcs bottle brush for hydroflask to try the market satisfaction. After receiving the brushes for one month, Tim contacted us and said that after this brush was sold as a companion product, many customers came to purchase the brush specially, which caused short supply. He urgently needed a large number of bottle brush for hydroflaskeand signed an annual contract with us.
