Ballpoint pen BIC 4 Colours Rainbow Mix model 529672, 0.32 mm stroke, blue/red/green/black ink, multi-color retractable pen

The BIC 4 Colours Rainbow Mix model 529672 is a retractable multi-colour ballpoint pen that integrates four ink options—blue, red, green and black—into a single compact instrument with a 0.32 mm line width. It is designed for precise writing, color-coded note-taking and quick corrections, combining convenience and versatility for everyday office, school and personal tasks.

Advantages

This multi-colour retractable pen offers the convenience of four ink colours in one handheld unit, eliminating the need to carry several pens. The 0.32 mm tip produces a fine, controlled line suitable for detailed writing and small handwriting. Its retractable mechanism secures the tip when not in use, preventing ink marks and making it easy to store in pockets or pencil cases. The combination of blue, red, green and black inks supports quick differentiation of notes and edits without changing tools.

Suitable for

• Note-taking and annotating textbooks or documents
• Color-coded planning, lists and schedules
• Editing, proofreading and marking corrections
• Everyday office use and administrative tasks
• Schoolwork requiring multiple ink colours without multiple pens

When it may not be suitable

This pen may not be ideal for users who require extremely bold or high-visibility lines, as the 0.32 mm tip is designed for fine writing rather than heavy marking. It may also be less suitable for long writing sessions if the user prefers a thicker grip or ergonomic design tailored to prolonged use.

Key specifications

• Ink colours: blue, red, green, black
• Tip size / line width: 0.32 mm (fine)
• Type: retractable multi-colour ballpoint pen
• Barrel: compact multi-cartridge housing with selector sliders
• Intended use: writing, note-taking, editing, colour coding

How to use

Select the required ink colour by pressing or sliding the corresponding colour selector. Write with light, consistent pressure appropriate for a fine 0.32 mm ballpoint tip to ensure even ink flow and prevent skipping. Retract the selected tip after use to protect the tip and avoid accidental marks. Replace the pen when ink flow becomes intermittent or the lines become faint.

What to consider before purchase

• Need for fine-line writing versus preference for broader tips
• Frequency of use and preference for retractable multi-pen convenience
• Requirement for multiple ink colours in one tool for portability
• Hand comfort and grip size for extended writing sessions

Usage recommendations

For best results, use on standard office or school paper and avoid pressing too hard to preserve tip life. Rotate between colours for balanced ink consumption and store the pen with the retractable tips closed when not in use.
