0.5mm ZENTO standard model uniball / uni

Soft Body Colors & Smooth Writing 🎨🖊️

A water-based ballpoint pen with soft, calm body colors.
Colorful, but easy to match with your notebook or desk.

The ink is ZENTO’s original black ink, developed for clear and clean writing.

New ZENTO Ink Technology ✨

This pen uses newly developed ZENTO ink.

Special “attracting particles” help control how the ink spreads.
Thanks to this, lines stay sharp and clear, even on paper that usually causes smudging.

・Less ink bleeding

・Less show-through on the back of the paper

Smooth Writing That Everyone Loves ✍️

A special cushioning ingredient (POA surfactant) works like a soft buffer
between the pen tip and the paper.

This reduces friction while writing
→ about 40% less friction compared to previous models.

Easy-to-Carry Clip 📎

The clip lets you quickly attach the pen to:

・A notebook cover

・A bag

・A shirt pocket

Easy to take anywhere.
