The Tombow Reporter 4 is a good old fashioned 4-colour pen, having black, blue, red and green inks inside. You'll notice the slightly unusual shape to the buttons. They're designed to aid in colour selection by touch alone, so you won't have to hold your pen and engage in the 'colour roulette', rotating the pen to find the colour you want! The Tombow Reporter 4 pen has a spring loaded feather clip and can be clipped anywhere. Matt rubber grip for comfortable writing. Attractive translucent barrel available in a choice of colours.
