# UNI-BALL Air Micro Pastel Colours - Variable Line (0.28-0.45mm) - Black Ink

This is a seasonal colour range for the popular Air rollerball. Ink colour is black and line width is Micro (0.28-0.45mm).

The Uni-ball Air is a low cost pen that feels quite similar to a fountain pen, but is very easy to use. The pen includes an air mechanism that varies the ink flow under pressure. If you press as you write or draw, you can increase the line width.

Uses Uniball’s pigment-based ink, which is waterproof, fade-resistant, and quick-drying, making it reliable for notes, journaling, or sketching.

It’s often described as a “gateway” pen for those thinking about fountain pens and is an excellent option for urban sketching. Ink dries within a few minutes, allowing you to then apply wet media over the top. 

Micro tip is 0.5mm (0.28-0.45mm line width).  
Fine tip available in the core range only and is 0.7mm (0.35-0.55mm line width).

Non-refillable.

Sold as a single pen.
