## Questions & Answers

**Q: are these pens fine or medium tip?**
A: I would say they are fine. The uni-ball air (without the micro part) are thicker if you need a thicker tip otherwise I would say these are similar to biro tips in terms of size.

### ⭐⭐⭐⭐⭐ Great pens
*by M***B on 19 January 2026*

These pens are great, ink flow and colour is perfect.

### ⭐⭐⭐⭐⭐ Good for junk journals etc
*by J***S on 26 December 2025*

Intense colour and good flow on lots of different textured surfaces. Recommended to me by a fellow crafter and I'm very happy with them.

### ⭐⭐⭐⭐⭐ Superb Pens!
*by C***Y on 2 August 2023*

This is my second box, I absolutely love the Micro air pens. I used to use another pen for years but once I tried these, I was hooked. I only use these now. I write alot of notes, letters and do various illustration work also and these are so fluid, smooth and create beautiful marks with the option of different thickness of lines but not needing to dent the paper which is great for what I need. They also seem to last extremely long also. 100% recommend!
