The Faber-Castell Goldfaber Aqua Dual Marker is a versatile water-based dye marker designed for artistic expression. It features two distinct nibs: a soft, flexible brush tip ideal for artistic work and a metal-encased fineliner tip that produces a precise 0.4mm line, perfect for contours and detailed work. Available in a wide array of colors, the ink is formulated to be odorless, acid-free, and pH neutral. These markers are fully water-soluble, ensuring they won't streak or bleed. Crafted from 100% recycled material, this marker supports both dry and wet artistic techniques.
