Small but mighty. The BIC 4 Colours Mini has all the features of a full-grown BIC 4 Colours pen. With blue, red, green and black you have 4 classic inks for creating a beautiful colour-code when writing, taking notes, drawing and outlining. That means it's the perfect pen for doing a bullet journal or to-do list and making the main idea stand out. The smaller 12 cm size is amazingly practical. It slips right into your pencil case, pocket or bag so you can always jot things down on the go. With the expertly engineered click-in/click-out system, switching between the different cartridges happens in an instant and the buttons don't get jammed.
