Mildliner brush pens are the newest innovation from Zebra. If you're a fan of the original Mildliners, these will be a prefect addition to your collection. They're currently produced in 3 color sets: warm, cool and pastel. These double sided brush pens come with a semi-firm brush tip on one end. The other end is a bullet tip finer than the bullet tip on the original Mildliners.
