The Inart 8021 No. 1 25mm Goat Hair Brush (110799083) is a flat brush made of soft and flexible goat hair, lightweight and easy to handle thanks to its reduced weight, even during prolonged work sessions. It is suitable for restoring sensitive documents, watercolor background washes, and applying diluted varnishes or primers, where the softness of the hair prevents visible brushstroke marks in the final finish. The long, flat, unvarnished wooden handle complements the handcrafted character of this tool, maintaining a comfortable grip even during longer and more detailed work sessions. The No. 1, the smallest in the 8021 range at 25mm wide, is suitable for smaller areas or work requiring more control than the larger sizes in the same line offer.
