Graphmaster Dual Tip Marker
These alcohol based twin-tipped markers have a fine (0.8mm) tip and a broad (7mm) tip. The markers are quick drying and water permanent. We have provided you with a selection of Cool Greys for shade variation and a pure black for contrast. Plus we have also included a colourless blender to mix tones and help blend the shades together. This mix of markers is perfect for practicing with tone variation without having to worry about colour choice.
