Use this super fine Pilot Super Color Gold Permananent Marker to write on most hard surfaces. It has a long lasting acrylic fibre tip and will even write on plastic, glass and wood. It looks great on dark surfaces, and the extra fine tip means it is perfect for writing on gift tags. This marker writes smoothly and the opaque, permanent Xylene free ink covers background colours without running or being absorbed. Easy to use, simply shake several times, remove the cap and press the tip down to start the ink flowing. These pens are best stored horizontally when not in use.
