Bristle is a stiffer, coarse, natural hair that often has flagged tips. Flagged tips are like split ends and hold more colour. Bristle is great for basecoats, heavy-bodied paints like oils and acrylics, and for adding texture. Chungking bristle hoghair with an interlocked bristle is specially prepared to give the best quality results over many years. We highly recommend these brushes to oil painters.
