I am using it only since I sold it by hand. It is hard to get dirty, hard to escape, no metal fittings, it is satisfactory to use it disposable. We would like to ask you to sell without dust so you can purchase large quantities.
Because it is a food factory, I use it with a machine, etc, but because the part of the brush is colored, the brush is not straight, it is strong because it is spiral. Just because there is extra tray, I wish I had only a brush.
