This Rainbow Dust Red Edible Pen is two sided with a thick & thin nib allowing you to work on whatever scale you require, from bold colour work right down to the intricate details of character model work! With the development of a specially formulated " Food Ink" this pen allows the ink to flow through a standard chunky nib, right down to a 0. 2mm nib. This nib is so fine that you can even use it for facial features on your sugar models. Much easier than using a brush for fine detail work!
