Round brushes are your usual go-to paint brush for doing watercolor. This brush is better used for doing detailed work because it has a smaller brush head than the typical Round 3 so it holds less paint. The smaller the number, the smaller the brush size.
Synthetic Sable Paint Brushes are the perfect go-to for any level of artist. Synthetic brushes are perfect for watercolor and gouache because they last longer than natural hair brushes and the bristles don't fall out while painting.
Proper care tips: Make sure to clean your brushes well after each use (with water) and only use these brushes with watercolor and gouache.
