Uni-ball AIR Micro Rollerball, 0.5 mm, Air-Tip Technology, Ultra-Smooth, Quick-Dry, Ideal for Everyday Writing - Black

Air-Tip Technology responds to your pressure as you write, delivering precise strokes and a controlled line. It helps maintain a steady ink flow, reduces feathering, and supports cleaner edges for tidy margins.

Key specs: 0.5 mm tip size for fine lines, fast-drying ink to minimize smearing for both left- and right-handed writers, smooth glide with a featherlight touch, and a balanced barrel designed for extended writing comfort.

Yes. The fast-drying ink and consistent ink feed help reduce smearing, making it a good choice for left-handed writers as well as right-handed users.

It's great for everyday writing tasks like taking notes, jotting to-do lists, writing letters, and drafting quick drafts where clean, legible 0.5 mm lines are preferred.

Use with the cap on when not writing. Remove the cap, start writing with a light touch, and avoid pressing hard. After use, recap to protect the nib and keep the ink flow steady. If the line becomes faint, gently shake or click the mechanism as per the product’s design to reseat ink flow.

Write with a light to moderate stroke, avoid heavy pressure, and ensure you are using the recommended 0.5 mm ink flow. The ink formula and air-tip mechanism are designed to minimize feathering and keep margins tidy.

The ink is non-toxic and designed for writing surfaces. Keep the cap closed when not in use and away from small children to prevent unsupervised access. Dispose of the pen per local regulations when it’s exhausted or no longer usable.
