Made with Sisal Fibres, these brushes make for great bottle cleaners, cleaning the bottle effectively yet gently(you'll see no scratches on the bottles).
 
The fibre is flexible enough to fit into a bottle of any size, and since the thickness of the fibre is the same overall, you'll get a thorough cleaning all though.
Ofcourse since they are natural fibres, they are good for the earth too!
 
Handling and Care: They are quick drying brushes and very low maintaninace. After use, simply ensure they dry thoroughly before storing.
