Bic BICMMP31 4-color Retractable Ballpoint Pen 1.0mm

Product Description

The BIC BICMMP31 is a retractable ballpoint pen with four ink colors in a single barrel. It delivers black, blue, red, and green ink through individual 1.0mm medium-point tips. The user selects the active color by extending the corresponding tip, enabling fast switching without reaching for a second pen. Each color cartridge is individually refillable, extending the service life of the pen body. This type of multi-color pen is used in office, field, and educational settings where color-coded notation, data entry, or document markup is part of a regular workflow.

The BICMMP31 is suited for general office and school use where multiple ink colors are needed in a single writing instrument. Common applications include annotating technical documents, marking inspection sheets, differentiating entries on logs or spreadsheets, and color-coded scheduling. The 1.0mm medium point lays down a consistent line on standard paper stock, making it practical for both printed forms and freehand notes.
