ShinHan Art TOUCH TWIN Fine & Broad Nib 24 Colour Marker Set An advanced alcohol-based ink formula that ensures rich color saturation and coverage with silky ink flow. The ink won't dissolve printed ink toner, allowing for odourless, vividly coloured artwork on printed materials. The delivery of ink flow can be perfectly controlled to allow precision drawing and the ergonomically designed rectangular body resists rolling on work surfaces and provides a perfect grip that avoids smudges and smears. A specially designed safety cap stacks neatly and prevents damage to the nibs. Each marker can work with one of four replaceable nib options to achieve a wide range of strokes, from fine lines to wide colour fills.
