Mattehop gel pens are a smooth writing pen with incredibly opaque ink, meaning you can write freely on pale or dark coloured card with ease. The pleasingly chunky 1mm nib means excellent coverage, even on coated paper. This set includes 14 incredible colours, presented in a bright box. When used on light coloured card they behave as a standard gel pen with vibrant ink colours. When use instead on dark coloured card, you'll see the ink magically transform as it dries, becoming even more vivid. Once dry, the ink has an almost plastic, matt finish. * High opacity gel ink * Can be used on coated or photography paper * 14 vibrant colours included * Excellent for drawing, colouring and calligraphy * 1.0mm tip
