An airbrush is a small painting tool that sprays paint, ink, or makeup in a fine, controlled mist using compressed air, allowing for smooth, even, and detailed application. It is commonly used in art, makeup, automotive painting, cake decorating, and model design because it creates soft gradients and professional-quality finishes that are difficult to achieve with traditional brushes. Most airbrush kits include a nozzle, paint cup, and air compressor, and they often allow adjustable spray patterns for precision work. Compact and versatile, an airbrush is ideal for both beginners and professionals who want detailed, flawless results. 🎨✨
