With the BIC 4 Colours Fluo ballpoint you can write in four colours with one ballpoint: blue, black, red and fluorescent yellow. The yellow pen has a thicker point with softer ink; ideal for underlining text. With the coloured sliders you choose the writing colour. The 4-colour pen has a colourful design that is partly transparent. The pen tip is fully retractable and the pen has a paper clip. BIC 4 Colours carries the NF Environnement ecolabel, for products with a lower impact on the environment.
