Bic Cristal Medium BallPen Blue, the blue ink version of the ever-popular ballpoint pens, still the market-leading after many years because they simply work well, are cost-effective, lightweight and write smoothly. The clear hexagonal barrel we are all so familiar with was originally designed to help you write with more control and the ball is manufactured from tungsten carbide for enhanced performance and extra durability, creating consistent writing without ‘skips’ or blobs. Bic affirms each pen contains enough ink to draw a 0.4mm wide line, two kilometres long! Key features: Blue ink Skip and blob resistant Long lasting and durable Smoother writing
