Ballpoint pen Biurfol 4-colour retractable medium tip — white and blue body

Biurfol 4-colour retractable ballpoint pen with a medium tip — white and blue body combines four ink colours in one compact instrument. The retractable mechanism lets you switch quickly between colours without changing pens, while the medium tip delivers consistent, legible lines for everyday writing, note-taking, editing and colour-coding. The white-and-blue barrel provides a neutral, easy-to-locate design suitable for office desks, school bags and home use.

Advantages

The pen integrates four distinct ink colours in a single retractable body, reducing the need to carry multiple pens and simplifying colour-coded tasks. Its medium tip balances smooth ink flow with controlled line width for clear handwriting and annotations. The selectable-colour mechanism operates with a concise push action for quick transitions between colours, and the compact, lightweight construction supports comfortable, extended use.

How to use

To select an ink colour, press the corresponding colour selector on the retractable mechanism until it locks into place; press a different selector to change colours. Retract the active tip by pressing the central release or designated retract button to switch to a different colour selector or to protect the tip when storing the pen. Use the medium tip with a standard writing pressure for consistent ink delivery; avoid excessive force to prevent tip damage or ink blotting.

Usage recommendations

Store the pen capped or retracted when not in use and keep it away from extreme heat or direct sunlight to preserve ink quality. If the pen is unused for a long period, operate the selectors occasionally to maintain smooth mechanism movement. For archival notes, test ink compatibility with paper type before long-term storage.
