Paint-It Acrylic Marker from Schneider.

Bullet-tipped marker filled with acrylic paint which is suitable for a very wide range of surfaces including paper, wood, cardboard, metal and stone. Thanks to valve-controlled application, the colour lays down evenly, with superb coverage, and dries quickly. The water-based paint is non-toxic and low odour.

Use indoors to give vividly-coloured new life to old furniture, or outdoors with a clear varnish sealant to protect against the elements.

To use, simply shake the marker a little, pump the nib a few times to get the ink to flow, then off you go! 4mm line width, for general work.
