Lyra Aqua Brush Duo
A fibre tipped pen with a double brush tip, suitable for artists, designers, and amateur painters of all ages.
The twin tips are very durable, and will produce the same high quality results for a long time. The broad brush tip allows you to use a technique similar to painting. The other tip can be used to draw thin, precise lines to create perfect drawings.
The water-based inks, available in up to 36 brilliant colours, can be mixed together. They can also be used like water-colours. You just need to apply the colours to a shiny surface such as a plastic sheet or an old CD and mix them with water and paint-brush to create some beautiful effects.
Sorry about the spanish video, they haven't made an english version yet, it gives you a good idea of how they lay down colour though.
