Chalk Mountain's New Small brush hits on all the "must haves" in a great brush. Painters look for these things in a smaller brush. Rounded Boar Hair Bristles which hold more paint...no rust ferrules....and a comfortable Ergonomic Handle which is Lightweight, heavy-duty wood handle in a well-balanced brush, this brush works with you, not against you. Important: Clean with soap and water but never soak your boar hair brushes. NOTE: Once Boar Hairbrush is used for a wax brush, we would recommend to not use the brush as a Paint brush, due to the wax coat left on the brush. We Guarantee our brushes & will replace any brush with a Manufacturer defect, free of charge. (photo must be presented for replacement).
