Use the Ackerman Pens Brush Ttool to wash your drawings or add color. Simply fill our Brush Tool with water and press it onto the back of you fountain or pump pen. It's that easy. Use any ink wash or watercolor — whatever flows best. A great way to add shading or tonal value to your artwork. 

Additional brushes are available in our shop. They're easy to replace. A great tool for travel kits as well.
