## Long description

Donau refill for automatic gel pen 0.5 mm with waterproof blue ink, supplied as a pack of 10, is designed for use in compatible click-action ballpoint and gel pens. The refill features a 0.5 mm fine tip that produces precise lines suitable for everyday writing and detailed note-taking.

Waterproof blue gel ink improves document durability and is suitable for records or materials that require resistance to water contact. The 0.5 mm fine point balances legibility and precision, and the pack of 10 provides ready replacements to maintain uninterrupted use of compatible automatic pens.

Ink color: blue
Pack quantity: 10 refills
Compatibility: designed for automatic (click) gel/ballpoint pens accepting standard 0.5 mm gel cartridges
How to use
Remove the used refill from the compatible automatic pen according to the pen manufacturer's instructions, and insert the Donau 0.5 mm gel refill until it seats firmly. Extend the tip using the pen's click mechanism and test on scrap paper to confirm smooth ink flow. Replace refills as needed when ink runs low or writing becomes faint, and store unused refills capped or in original packaging to prevent drying.
