Koi Water Brushes are designed for the easy transportation and storage of water when you're away from home or the studio. The brush separates into two parts: a fine, flexible brush tip, and a barrel handle with a plug to carry the water. The comfortable grip is great for controlled blending, shading, and highlighting. The Koi Water Brush is available in three brush and two barrel sizes for maximum versatility. For ages 3 and up. WARNING: CHOKING HAZARD - Small Parts. Not for children under 3yrs.
