Zebra Pen Corporation 82712 marker refill black bold 2 pack

Compatible refill pack for Zebra pens

This two-pack of black bold refills fits the F-301, F-301 Ultra, F-402, 301A and Spiral ballpoint models. Acid-free, archival-quality ink keeps important documents legible over time. The conical tip produces consistent lines without skipping. Buyers using other pen brands or tip sizes will need a different refill.

Two refills per pack for extended use

Each pack supplies two bold-point cartridges, doubling the writing life before a reorder is needed. Black ink delivers high contrast on standard office paper. The bold point size suits signatures and headings but may feel too broad for fine notes or narrow forms.

Conical tip and acid-free formula

The conical tip resists wear and maintains its shape through daily writing tasks. Archival-grade ink prevents fading and paper degradation in filed records. No specialised tools are required to swap cartridges in the supported Zebra models.
