Lyra Aqua Brush Duo 6 serves as the perfect introductory palette or portable expansion, packing six professional, water-soluble markers featuring an innovative dual-tip layout for total creative flexibility. Each pen integrates an elastic, highly resilient nylon brush tip on one side for broad watercolor washes and calligraphy, perfectly counterbalanced by a stable fine tip on the opposite end for sharp precision detailing. Engineered with an odorless, non-toxic, water-based ink system, these German-quality markers blend flawlessly together on paper or can be easily activated with a wet brush to create smooth, transparent watercolor washes without paper fraying.
