Stylus brushes are specialized tools used primarily in digital art and design. They feature a soft, flexible tip that mimics traditional paintbrushes, allowing artists to create various textures and effects on digital canvases. Stylus brushes are commonly used with graphic tablets and devices like the Apple Pencil or Wacom tablets. These brushes can be customized in software applications such as Adobe Photoshop or Procreate, enabling artists to adjust size, opacity, and other settings. This versatility makes stylus brushes popular among illustrators, graphic designers, and hobbyists who want to achieve a more natural painting experience in a digital format.
