The marker has non-toxic, alcohol based ink which produces bright and vibrant colours. The ink will dry acid-free on paper. Features • This marker has a broad nib on one end and a flexible brush nib on the other. • These markers are perfect for a variety of art styles including illustration, manga, fine art and more. • The ink dries acid-free, ensuring that it lasts longer and does not interact with your paper. • The marker is printed with the colour name and number, making it easy to find the right one. • Colours in the same family can be blended together or you can use other markers to draw directly onto the nibs without worrying about cross contamination. • The brush nib has a hard wearing design that will bounce back into shape no matter how hard it's pressed.
