Review: Good pens - Great pens. Smooth ink flow and lasts several months or more. Ink dries quick and doesn't smudge.
Review: Always perfect - The UB-105’s and 157’s are my favourite roller ball pens for writing and drawing. Great selection of bold colours (apart from the dark green which is a bit insipid). Excellent pens well recommended.

## Questions & Answers

**Q: Are these refillable?**
A: No

**Q: Are these the real ones?**
A: That's questionable. The uniball micro only comes in 3 colours (black, blue, red). The uniball fine comes in green. But all these pens say micro.
