KINGART Original Gold 9550A Square Wash brush, designed for mixed media painting with premium Golden Taklon synthetic filaments. The waterproof acrylic handle features a beveled end that doubles as a scraper or palette knife, while the wide, flat square wash head holds large amounts of water and color for efficient washes, backgrounds, shading and highlighting. Filaments are blended in three diameters and lengths for excellent absorption, fluid retention and natural snap, returning to shape after use. Nickel-plated brass ferrules are crimped for a secure bond, and the ergonomically balanced handle reduces hand fatigue for extended painting sessions. Suitable for oil, acrylic, watercolor and gouache, this vegan-friendly, handcrafted brush offers durable performance and precise control.
