Question 1

What makes the Uni-ball Uni Pin Fineliner 0.5 mm ideal for technical drawing?

Accepted Answer

It uses archival pigment ink, a 0.5 mm fine point, and a metal-clad tip that resists wear when used with rulers, delivering precise lines and clean scans.

Question 2

What does archival pigment ink mean for my drawings?

Accepted Answer

Archival pigment ink is water- and fade-resistant, so lines stay legible and dark over long periods, even with repeated handling.

Question 3

How does the 0.5 mm tip perform on rulers and templates?

Accepted Answer

The metal-clad tip provides extra durability, keeps a consistent line when you guide the pen along edges, and helps prevent tip wobble on straight lines.

Question 4

Will the ink smudge when I write over it or scan my page?

Accepted Answer

No. The quick-setting pigment dries rapidly to reduce smudging, making it suitable for tidy overwriting and clean scans.

Question 5

What are the key specifications of this Uni Pin fineliner?

Accepted Answer

0.5 mm tip, archival pigment ink, waterproof and fade-resistant, metal-clad tip, smudge-resistant, snap-cap for cap-on cap-off use.

Question 6

What are common use cases for this fineliner?

Accepted Answer

Technical drawing, architectural notes, precise labeling, notebook journaling, and detailed line work on sketches.

Question 7

How should I care for and use this pen to maximize longevity?

Accepted Answer

Keep the cap on when not in use, store upright to protect the tip, and use on smooth, clean paper to minimize tip wear and ink feathering.

Question 8

What are some good alternatives on Fepy.com for 0.3 mm or 0.8 mm variants?

Question 9

How does this compare to a Pigma Micron 0.5 mm fineliner?

Accepted Answer

Both offer crisp lines, but Uni Pin uses a pigment-based archival ink with a metal-clad tip designed for durable lines on rulers, while Pigma Micron is another popular archival ink option. See: https://fepy.com/product/pigma-micron-05-mm-black

Question 10

Is the Uni Pin 0.5 mm fineliner refillable or replaceable?

Accepted Answer

Most Uni Pin fineliners are not designed to be refilled; once empty, the entire pen is typically replaced.
