Ballpoint pen Centrum Pioneer 3-color — retractable 3-ink cartridge, plastic barrel

The Centrum Pioneer 3-color ballpoint pen is a retractable multi-ink writing instrument with three selectable ink colors integrated into a single lightweight plastic barrel. Designed for note-taking, editing and color-coded writing, this pen houses three ballpoint cartridges that switch with a simple selector mechanism, allowing fast changes between colors without replacing pens. The compact, retractable design keeps tips protected and makes the pen convenient to carry in pockets, pencil cases or notebooks.

Advantages

The three-color functionality enables quick color changes for annotations, highlighting and organization without multiple pens. A retractable mechanism secures the tips and prevents accidental marks. The plastic barrel keeps the pen light while providing a stable grip for everyday writing tasks. Compatible with standard ballpoint ink behavior, it offers consistent lines suitable for schoolwork, office tasks and personal planning.
