The Faber-Castell Albrecht Dürer Magnus Watercolor Pencil is a pretty big deal! With a 5.3mm core, it’s ideal for large-scale drawing. The jumbo size is gentle on the wrist, so you can use it for long periods of time without discomfort. This 100% water soluble pencil remains extremely vibrant dry or wet, thanks to its high pigment density and maximum lightfastness. When brushed with water, the pencil marks melt onto your paper and intensify in color.
