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.

• Tip Size: 0.7 mm (line width 0.35 mm).
• Length: 120 mm.

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.
