Sanford uni-ball 207 Impact Gel Pen Refill Bold Black 2/Pack 396571

Refill pack for uni-ball 207 Impact pens

This two-pack supplies black gel-ink refills built for the uni-ball 207 Impact gel stick pen. Each cartridge uses a 1 mm bold conical tip that lays down thick, vibrant lines. The pigment-based Super Ink formulation bonds with paper fibres to resist alteration, water damage and fading. Professionals who sign documents or keep permanent records will appreciate the secure, archival-quality output.

Practical limits of the standard gel refill format

The refill follows the standard gel cartridge profile specified for the 207 Impact series, so it fits only that pen family. Ink flow is calibrated for the 1 mm tip; using the cartridge in a different barrel may cause skipping or leaking. Quick-drying chemistry reduces smudging on most papers, but very glossy or coated stock can still show minor set-off. The pack contains exactly two units, so high-volume users will need multiple packs.

Stainless-steel tip and everyday handling

An ultra-durable stainless-steel tip resists bending and breakage when the pen is dropped or carried in a pocket. The smooth-glide conical point maintains consistent line width without scratching the page. Refills are packaged in a compact blister that protects the nib during storage and transport. Swapping a used cartridge takes seconds — pull the old unit out and press the new one in until it seats firmly.
