Tombow Dual Brush Pens feature vibrant, water-based ink that blends beautifully, layers effortlessly, and activates with water for soft, watercolor-style washes. Create smooth gradients, custom hues, or ombré effects with total control.
 
Each pen offers two tips for maximum versatility—a flexible brush for bold strokes, fills, and lettering, and a fine tip for clean lines and precise details. Both tips pull from the same ink reservoir for consistent color every time.
