Mildliner Brush Pen and Marker Set features a double-ended design to provide both a paint brush-like tip and fine-tip marker in one writing tool. Soft, mild ink is translucent to easily layer colors and 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 and acid-free for lasting results. Fluorescent color palette includes pink, orange, yellow, blue-green and blue.
