Professional Large Watercolor Mop Brush This extra-large squirrel hair watercolor mop brush is designed for artists who need maximum water capacity and smooth flow control when working on large washes and backgrounds. Crafted with natural squirrel hair, the brush excels at holding and releasing water gradually, making it ideal for wet-on-wet techniques, skies, landscapes, and soft color transitions. Compared to synthetic brushes, squirrel hair carries significantly more liquid, reducing the need for constant reloading and helping maintain consistent washes. The handmade mop construction creates a full, rounded body that stores pigment efficiently while still forming a natural point. Even in large sizes like 11 and 14, the brush remains predictable and easy to control, allowing artists to move seamlessly from broad strokes to softer shaping. This brush is especially recommended for: Large background washes Skies, water, and atmospheric effects Smooth gradients and soft blending Watercolor, ink, and wash techniques Care Instructions: Rinse gently with clean water after use. Reshape the hair and allow to dry horizontally or with the tip facing down. Avoid soaking for long periods to preserve the natural hair.
