INART wide 4mm water brush with reservoir.

The Inart Water Reservoir Brush offers comfortable handling and paints smoothly. With a large water reservoir and a button for easy control of water release, this brush is ideal for use with watercolors, gouache, and watercolor pencils. The soft bristles are made of durable and flexible nylon fiber, which retains its original shape after use. Portable and ideal to take wherever you go, as the reservoir remains sealed so that water does not escape unless the button is pressed.
