Promarker Watercolour combines the bold and sharp qualities of a marker with the subtlety of colors and effects of watercolor paint in a portable marker perfect for on-the-go sketching and painting. The twin-tipped markers have a fine point on one end and a flexible brush on the other, helping you create a variety of line thicknesses and detailing. Water-based pigment ink allows for flexibility to come back to your work at any time as you can reactivate the ink with water. The markers contain high-quality pigments so your work will not fade.
