uni-ball - Signo Gel Grip, Fine Nib, Red Ink, Rollerball Gel Pens (12pc Set) - Smooth, Comfortable, Long Lasting, Japanese Quality, for School, Work, Office, Study, Teacher, Notes, Journal, Gift

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...

Nice thick 0.7 nib excellent for marking up and visible

Alway use a brand of fountain pens. The ink I've used is no longer available, and the pens don't work right without that. Therefore borrowed one of these and they were so good "I bought the company" ! They are very nice. The get used up quickly but they are nice and reliable, and write smoothly. Barrel a little thin but they are very good.

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

Exactly what it says on the tin. Lovely smooth writing, dark black ink, dries fast (but will smudge very lightly if you wipe it too quickly). I tested this with a Moleskine notebook to see how much the ink shows through compared to a Legami erasable pen. It doesn’t bother me that much but is noticeable and may bother some folk but that’s just a drawback of using gel ink in a Moleskine.

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.

Solid reliable pens

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).
