Frequently Asked Questions

Q: Will the S210 refill fit my Deli pen?

A: The S210 refill is confirmed compatible with the Deli S99, NS554, and NS552 retractable gel pens. If you have a different Deli model, check the label on your current refill — if it reads „S210“, this pack is a direct replacement.

Q: Is this an official Deli product?

A: Yes — the Deli S210 is the manufacturer’s own replacement refill, produced to the same specifications as the refill included with your original pen.

Q: What ink color is available?

A: This listing is for black ink only, in 0.5mm tip size. Black is the standard choice for everyday writing, exams, and official documents.

Q: How long does each refill last?

A: Ink life varies depending on writing pressure and usage frequency. Under typical office or study conditions, each refill provides several weeks of regular use. The 12-pack ensures you always have a spare on hand.

Q: Can I use this refill in non-Deli pens?

A: The S210 refill is designed for Deli pen models. It may fit other brands with a similar refill format, but compatibility is not guaranteed. We recommend verifying the dimensions against your current refill before use.

Q: Is the ink quick-dry or smear-resistant?

A: Yes — the gel ink formula dries quickly on standard paper, minimizing smearing. It is suitable for both right- and left-handed writers.
