Chameleon Fineliners have a patented dual ink system, with ink in the pen and in the cap. To instantly blend colours, all you have to do is switch the cap, or hop the top to another pen, leave it a few seconds and make vibrant colour to colour blends. The newest addition to the Chameleon family, Chameleon Fineliner, are elegantly crafted to incorporate the same Chameleon colour blending technology, but in the form of an ergonomic, fine point Japanese precision 0.3mm metal-clad tip. Waterbased dry safe ink, won't bleed through most papers. Ideal for journals, planners, colouring, drawing, sketching and every day writing.
