The brown gutter brush looks simply, but it is not easy to make. The brown gutter brushes before were neither able to filter well, or the workmanship was rough and often lose filament.
Aoqun recommended the best-selling brown gutter brush. Aoqun is a brush processing factory specializing in brown gutter brushes, so it will launch different brown gutter brush products at any time according to market demand.
In order to prevent the filament from loosening, the brown gutter brushes are strictly tested at the factory to withstand the pull-out force to ensure that the brushes will not lose filament after the biofilm is loaded.
