Uni Zento Gel Pen Refills

Variant
$1.50
UBR-Z refills are designed for use with the Uni ZENTO extended pen lineup and are available in black ink in 0.38 mm and 0.5 mm tip sizes.

These refills use Uni’s newly developed ZENTO ink, created for an ultra-smooth, low-stress writing experience. Cushioning POA components help absorb friction between the pen tip and paper, reducing drag by about 40% compared to Uni’s standard water-based ballpoint ink. The pigment-based formula also controls ink spread, delivering crisp, clean lines with minimal bleeding or show-through.
