This vibrant collection of Duo tipped Adult Colouring Markers by Mont Marte are exceptional quality for adding a dash of colour to your page. The 24 beautiful colours are packaged in a neat plastic case which makes all of your markers easy to find and access when you are drawing or colouring in. Each Duo Marker has dual tips at either end of the pen. One is a fine tip for rendering crisp, clean line-work, the other is a brush tip for smooth and even colour application.
