UM151S SigNo Gel Rollerball Comfort Grip 0.7mm Tip 0.5mm Line Black Ref UM151BLK [Pack of 12]

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...

My son’s favourite gel pens for university.

The item was exactly as described. Have been using them for a while and they are so easy to write with.

Love these pens, well worth the money. Arrived on time and well packaged.

Easy & comfortable to use.

As described good value for money

Promptly sent, my favourite pens.

I prefer these pens to any other, have used and bought as presents. Ink is very clear, good value

Tutto bene, ottima scorrevolezza

Best ball pen that I have used. Leaves uniform trail ALWAYS.

Die Stifte und ziemlich gut und scheinen nicht durch, schreiben über Tippex und sind so ziemlich zuverlässig. Manchmal klecksen sie etwas beim Schreiben, oder sie schreiben gar nicht, aber wenn man etwas schüttelt geht es dann wieder.

Great pen that isn’t too small or too big. Writes cleanly without blotches.

I love these pens; they are perfect. Second box I have bought in 2 years. They last a while; each pen lasts me about a month or 2 (I use it in rotation with purple pens for marking students' work).
