Box of 12 BIC 4 Colors Fluo yellow ink ballpoint pens

Underline in fluorescent with the 4 Couleurs Fluo, an almost normal 4-color BIC pen. 
His particuliarity ? 
You will find the classic black, red, and blue leads but instead of the often less used green lead there is a tip with fluorescent yellow ink. 
A real smart pen that allows you to write and highlight. Éso much wider than the others, the fluorescent lead allows you to highlight, surround and underline the most important information while allowing the text below and the annotations left by the other leads to appear. 
With its translucent design, its total FLUO look brightens up the planet of 4 colors.
