Review: Good quality pen, free flowing ink and non-scratchy nibs. Best of all though, hard to beat at this price! - This review applies to the UM-151S red gel-grip rollerballs, as there seems to be a mush-mash of options covered by the same review process. The gel grip gives more purchases than a cheap shiny plastic body, I like the feel of these pens in my hand as they are well balanced. The cap has a *very* firm click as it locks into place, so is unlikely to fall off or get lost in a bag or whatever. The pigment gel ink and stainless steel tip combination works well to produce a consistent and non-scratchy flow when writing. I usually prefer a finer nib/tip/ball to be honest, but as you can see from my attached photo the 0.7mm one of these pens isn't exactly thick or clumsy. I couldn't find any 0.5mm tip red pens that matched these for value, so here we are. Great value, and this box of 12 will almost certainly see me through until this time next year I reckon. Shame I can't find a red Parker 'quink' rollerball refill though, as I'd rather keep a single pen and just refill rather than buy disposables - but hey ho...
Review: Too quality gel - My son’s favourite gel pens for university.

## Questions & Answers

**Q: Can you get refills for these pens?**
A: As far as I can see one cannot replace any part of these pens.
However, at these prices for 12 pens, I don't really see the need.

**Q: Can anyone tell me what the difference is with the 151S and the 151 please? Thanks**
A: I think that the 151 s is thicker
