Goldfaber Aqua Dual Marker from Faber-Castell combines a thin tip full of detail with a flexible brush tip. The ultimate combo for sketches, contours, lettering and colouring. The ink is water-based, which means it won’t bleed through the paper, and water-soluble, which means that it can be used for delicate watercolourings. Caps and barrel are made entirely from 100 % recycled plastic. Odourless, acid-free and pH neutral ink. Line width fineliner tip 0,4 mm.
