DeSerres Snow brushes are made with longer-lasting synthetic hog hair bristles, which are more durable and better suited for a wide range of mediums than natural bristles. Designed to look and feel like hog bristle brushes, these brushes are perfect for painters who quickly switch from oils to acrylics or water-soluble oils. The E Set includes four long handle paintbrushes: #8 Bright, #10 Filbert, #6 Filbert, #4 Round. Paintbrush care: Paintbrush care is essential to maintaining their condition and extending their life span. Always clean brushes before the paint dries. Using a hydrating paintbrush cleaner after using Taltine or soap prevents bristles from drying and helps maintain their suppleness. Watercolour: clean with warm water Oil: dip the paintbrush in a solvent such as Taltine; clean with warm soapy water and a clear water rinse Acrylic: clean with warm soapy water and a clear water rinse
