When do you need refills?
Refills are the ideal solution when your favourite ballpoint pen is empty but still works perfectly. Instead of buying a new pen, you simply replace the empty cartridges and give your ballpoint pen a second life. This is not only cost-efficient, but also more sustainable than constantly buying new pens.

Why choose this 5-pack?
With five refills in one package, you have enough stock for a long time. You don't have to reorder cartridges every time a pen runs out, which is especially handy in the office, where ballpoint pens are used intensively. The blue colour is the most commonly used office standard for official documents and correspondence.

Document-proof ink for professional use
These cartridges contain document-proof ink, meaning your handwriting is permanent and tamper-resistant. This is essential when signing contracts, filling in official forms or other important documents where the ink must not fade or be erased. The plastic casing protects the ink supply from drying out.

Compatibility and practical tips
The cartridges are 105 mm long with a medium line width, suitable for herlitz ballpoint pens that require this specific cartridge size. Check that your ballpoint pen is compatible with this size before ordering. Store unused cartridges at room temperature and away from direct sunlight to preserve ink quality.
