Faber Castell's Goldfaber Aqua Dual Marker is a water-based dye marker featuring two nibs: a soft flexible brush tip for artistic work and a metal-encased fineliner tip which creates a 0.4mm line for contours and finer details. Available in a range of colours, the ink is odourless, acid-free and pH neutral. These markers are fully water soluble and will not streak or bleed. Made from 100% recycled material. This marker is part of the Creative Studio brand, enabling both aspiring and hobby artists to express and enjoy their creativity. It's a modern creative tool for a large audience, featuring a thick brush nib for fine to thick lines and larger areas, and a thin nib for fine drawing, contours, lettering, and accents. Available in 60 attractive shades, it's ideal for both dry and wet techniques. The ink is fully water-soluble, streak-free, and does not bleed through the paper. Caps and barrel are made of 100% recycled material and may show colour variations due to production. The ink is odourless, acid-free, and pH neutral.
