The Zebra Mildliner Brush is conveniently double-ended with a paintbrush-like tip and fine marker in one pen. The brush tip is like an artist's brush allowing for thick or thin strokes while the fine tip marker provides more consistent lines and controlled marks. The soft Mildliner color is translucent and excellent for layering. The acid-free pigment-based ink is water-resistant and doesn't bleed through most surfaces. The Fluorescent 5-Color Set contains blue, blue green, yellow, orange and pink.
