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.
