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.
