The classic BIC Cristal Original pen with its clear barrel is the world’s best-selling ballpoint pen, and this pouch of 10 contains 4 blue, 2 black, 2 red and 2 green ink pens. These lightweight pens has enough ink to write for an average of 3 km (blue and black ink only), plus is certified with the NF Environnement eco-label. The minimal design of this iconic object has made it part of the permanent collections at the New York Museum of Modern Art (MoMA) and the Musée d'Art Moderne/Pompidou Centre in Paris.
