Ballpoint pen BIC 4 Colours Smooth Gradient, 4-color retractable ink (blue, red, green, black), round barrel, tip S

The BIC 4 Colours Smooth Gradient ballpoint pen combines four retractable ink options—blue, red, green and black—in a single round-barrel instrument. Designed with an S-size tip, it delivers consistent lines for everyday writing, note-taking and color-coded marking. The retractable mechanism allows quick switching between colors without the need to carry multiple pens, making it a compact choice for students, professionals and mobile use.

Advantages

This four-color pen offers convenient, instant access to multiple inks in one handheld tool, reducing desk clutter and simplifying color-coded tasks. The round barrel provides a familiar, ergonomic grip for general writing sessions, and the S tip balances smooth ink flow with controlled line width. Retractable sliders keep tips protected and prevent accidental marks when the pen is stored.

Suitable for

• Everyday note-taking and journaling
• Office tasks, document annotation and quick edits
• Students for highlighting, organizing notes and exam practice
• Color-coded lists, schedules and simple diagrams

When it may not be suitable

The S-size tip is intended for general-purpose writing and may be too fine for those who prefer broad, high-impact strokes or for tasks that require heavy shading. The pen is not designed for permanent archival marking on non-paper surfaces or for specialized art techniques that require variable nibs or refillable ink systems.

Key specifications

• Ink colors: blue, red, green, black
• Tip size: S (standard fine)
• Barrel shape: round
• Retractable multi-color mechanism
• Intended use: ballpoint ink for general writing

How to use

Select the desired color by pressing the corresponding color slider until it clicks into place. Write with steady pressure suitable for ballpoint ink; avoid excessive force to maintain consistent lines and prevent tip wear. To retract a color, press a different slider or the same one as provided by the mechanism. Store the pen capped within its body when not in use to avoid accidental marks and to keep the tips clean.

What to consider before purchase

• Confirm the S tip width suits your handwriting and preferred line thickness.
• Consider whether a multi-color retractable pen meets your needs versus separate pens or specialized writing instruments.
• Assess preferred ink colors and how often you switch between them during typical tasks.

Usage recommendations

For reliable performance, use the pen on standard paper and allow minimal pressure while writing. Switch colors with deliberate clicks to ensure the selected refill is fully engaged before writing. Keep spare single-color pens or refills available if extended heavy use is expected.
