The Lyra Aqua Brush Duo is a high-quality dual-tip brush marker. The fine tip allows for precision, patterns, and detailing, while the wide, flexible brush head creates soft, clean strokes. With nylon fibres that provide elasticity for larger surfaces and stability for finer strokes and lettering, the Aqua Brush Duo is favoured by designers, cartoonists, and graphic artists, making it ideal for calligraphy and lettering. Its water-soluble colours are odour-free and non-toxic.
