With pink, purple, turquoise, and lime green inks, the BIC 4 Colours Fun pen adds some zing to your notebook. It was originally created as a novelty edition to celebrate 40 years of the BIC 4 Colours pen, but this Ã¢ÂÂfunÃ¢ÂÂ version became a household name in no time. It comes with 4 vibrantly coloured inks for taking notes with a touch of whimsy, creating a beautiful colour-code or livening up your bullet journals and to-do lists. BIC product design is always based on function, so the barrel on the 4 Colours Fun ballpoint pen also has a choice of 2 cheerful colours: sky blue and lilac. The 12 light blue pastel barrel BIC 4 Colours Fun retractable pens included in this box will spice up your pencil case as well as your notebook. When BIC was founded in 1950, it began by specialising in ballpoint pens so its expertise is second-to-none. As a mark of quality, the ballpoints in the BIC 4 Colours Fun pen are engineered down to the micrometre to keep the ink flow flawlessly even for fluent smudge-free writing. This pen comes in many versions to satisfy a range of styles and uses. First came the BIC 4 Colours Original pen followed by its variations: Shine, Decor, Charm, Grip, Pro, Fine, Fluo, 3+1 HB Lead.
