Airplane-safe: An automatic pressure equalization prevents the markers from leaking on board aircraft. Ideal for use on paper as the ink does not bleed through. Washes out of most textiles. Colour-intensive and odourless. Water-based ink. Dries in seconds, making it ideal for left-handed users. Comes with a clip. The PP barrel and cap guarantee a long service life.
