Mildliner Highlighter is conveniently double-ended with a chisel tip and fine marker in one pen. The mild water-based pigment ink is translucent, excellent for layering and doesn't bleed through most surfaces. The chisel tip allows for thick or thin strokes while the fine tip marker provides more consistent lines. Fineliner pen is great for underlines and notes. AP certified non-toxic. This set contains Mildliners in yellow, blue, green and pink, and Sarasa Fineliner in black.
