The DeSerres paintbrush in synthetic sable is supple, resistant, offers good liquid retention and is suited for watercolours and acrylics. The DeSerres paintbrushes are an excellent value. Care: Caring for paintbrushes is essential to keeping them in good working condition and to their life span. Watercolours: dip the paintbrush in water and rinse in warm water. Acrylic: clean in soapy water and rinse in warm water. Practical information: Never let dry before cleaning. Using a hydrating paintbrush cleaner after using taltine or soap prevents bristles from drying and keeps the supple shape of the paintbrush.
