The Aqua Brush by Pentel is an innovative water tank brush specifically designed for watercolor painting and the use of water-soluble colors and pastels. With a refillable water tank of 10 ml, this brush allows for precise and controlled application of water, as it can be finely dosed by applying pressure to the casing. The shape-retaining nylon bristle tip ensures even color distribution and allows for both fine and broad strokes, depending on the need. The Aqua Brush is ideal for artists who value flexibility and ease of use. It offers a practical solution for painting on the go, as it does not require a separate water source and is easy to transport. With this brush, creative ideas can be effortlessly realized, whether in the studio or outdoors.
