Mildliner Brush Double-ended Creative Markers feature a double-ended design to provide both a paint brush-like tip & fine-tip marker in one writing tool. Soft, mild ink is translucent to easily layer colors & will not bleed through. Brush tip is like an artist's brush to create thick or thin strokes. Fine tip creates sharp, precise lines for detailed use. Reusable storage case keeps everything neatly organized. Pigment-based ink is water-resistant & acid-free for lasting results.
