Tombow Dual Brush Pens have two nibs: one fineliner and one larger brush, which is springy and allows for a wide range of naturalistic stroke sizes. Their color is saturated and bright, and can be blended with water; they're always fun to use. They're perfect for fine art and craft projects, journaling, coloring books, and field work. The water-based ink non-toxic, odorless, easily blend-able, and won't bleed through most papers.
Not refillable.
