Uni-Ball Air – 0.5mm Rollerball - Blue, Green, Pink and Orange Barrel - Black Ink – Pack of 4 - UBA-188E-M

Those pens are amazing, no smudges, quick dry. Perfect is the word to describe them in my opinion, but received wrong ink colour.

I love the way these pens write, they come in cool different colours and last a while. Recommended

Yes I did the classic and looked and the picture and not the title. Yes they are lovely and colourful looking pens but they are all black ink. My fault there so no stars deducted for that. They do write incredibly smoothly, and they are pressure sensitive so the harder you press, the thicker your line. I've quite heavy handed and have been working hard to put less pressure on. But even when trying to be as light as possible, I do find the ink takes a little longer to try than other pens. I do get the occasional pen smear on my hand on slight smudge on the paper if I'm writing quickly. I probably wouldn't use these for heavy note taking for this reason, but for small amounts of writing they're lovely. My final point, and this may just be my taste, but they were capped in mismatching colours like in the picture. The thought of what kind of a monster would do this is quite distressing. But I quickly resolved it and they now live with their correct lids in a neat line at stationery village.

The best ballpoint pen you can buy (without selling a kidney)

I have been using these for years and originally found them in the high street. But they stopped selling them. I was so glad I found them on Amazon. The fun part is that the tops and bodies are different colours so you can mix and match them. When I was a child we had a saying "Little things please little minds". Well these please me. They write well too and last for years. Just make sure you get them back if some one borrows one.

These are vibrant looking pens which write really well. The only downside is if you are using cheap, thin paper it bleeds through to the other side but it writes like a quality pen if you buy decent paper! I will certainly buy again.

Ink only half filled so pens run out very quickly. Not worth it.

For an everyday pen, a notetaking pen, a school pen, these are hard to beat. More or less tamper proof, they're perfect for people who end up covered in ink because they fidget and take pens apart. I prefer a broader nib myself, but these are great to write with, and rival a fountain pen for smoothness and comfort.

Whilst the description of the product says black ink, what came was blue ink. I am extremely particular hence returning the product

Me encanta como escribe éste bolígrafo

alles super

I love that although they were florescent looking colors on the outside, they were all black ink. Every time I broke my pen out to sign things, every single person commented on how awesome my pen was. They loved it even more with the way it looked and felt when you wrote with it. If you're not looking too closely, it seriously looks like you are writing with a marker, just looking at the tip alone. But it comes out thin looking...I love these pens and if more colors come out, I'm getting them!

Desde que los descubrí no he dejado de usarlos y pedirlos. Nunca se han descargado. Duran mucho y escriben muy bien, no importa si los has dejado mucho tiempo abiertos.
