The medium tip offers control for creating both intricate lines and broader motifs, making it suitable for detailed artwork or quick sketches. It can be layered or blended with other colors for versatile creative effects. The marker must be activated before first use by shaking vigorously, then pressing the tip onto a test surface until ink flows. Store horizontally at room temperature. Made in Germany, this high-quality acrylic marker is perfect for artists working on light or dark surfaces, including canvases, acrylic paper, and painting boards.
