UNI SXR-C7 Refill – Unmatched Writing Smoothness
Product: UNI SXR-C7 Refill (Black), 12 pcs pack
Many users struggle with skipping or smudging pens, especially during long writing sessions. The UNI SXR-C7 refill, featuring revolutionary Jetstream technology, is designed for those who demand speed, quality, and reliability on paper.
1. Innovative Jetstream Writing Experience
This refill stands out due to its low-viscosity ink, which allows the pen to glide across the paper without any resistance. It’s more than just a pen refill; it’s a tool that reduces hand fatigue:
- Smoothness: Zero friction or "scratchy" writing feel.
- Quick Drying: The ink dries almost instantly, making it an excellent choice for left-handed writers who often smudge their work.
2. Archival Quality and Security
Unlike standard writing instruments, the UNI SXR-C7 uses pigment-based ink that is highly resistant to external factors. This is crucial for signing official documents or archiving notes.
- Water Resistance: Even if the paper gets wet, the text remains legible and doesn't bleed.
- UV Resistance: Your notes won't fade even after prolonged exposure to direct sunlight.
3. Versatility and Precision
While this refill is tailor-made for the popular SX-217 model, its standard 12 cm length makes it compatible with many other non-retractable pens. The 0.7 mm tip produces a neat 0.35 mm line, offering clarity while allowing for detailed and compact writing.

Frequently Asked Questions (FAQ)
Does this refill only fit the UNI SX-217 model?
It is specifically designed for that model, but due to its standard 12 cm length, it fits many other non-retractable (capped) pens as well.
How does Jetstream ink differ from standard ballpoint ink?
Jetstream ink has lower viscosity, meaning it writes much more smoothly than traditional oil-based ink and dries significantly faster than gel ink.
