Great quality pens, by far the best of all rollerballs in my mind! Wine red is a lovely colour.
Uniball Eye Pens are of superb quality. They write delightfully smoothly with no scratchiness or smudging whatsoever. And they come in a range of different colours. I use them regularly and they last for a long time so are well worth the money. Buying them in packs makes them even more good value for the price.

It is as described
Sold in a snap baggie, but genuine pens. I like the colour and this ink doesn't bleed through the paper. Nice flow to my writing.

Works well, light in weight with varying widths.
I bought a Uniball instead of an ordinary biro just to try, and I have never stopped using them! No more scrubbing the pen on a scrap bit of paper to get it working. The Uniball writes first time every time with clear black line, light in weight this pen is very good value for money compared to some others. Pens come with varying sized tips according to your needs or fancy, I use a 0.7mm tip for handwriting which suits me fine! If you buy one keep a hold of it as anyone who borrows it may decide to keep it!

Great for note taking
Lovely pens to write with, very smooth with very little blotching. Can smudge if you don't let the ink dry for a couple seconds. They last a long enough time to make the cost worth it.

Feiner Stift der sehr lange hält...
Sehr feiner Stift der auch lange hält. Man kann sehr gut den Tintenvorrat ablesen. Mein Kritikpunkt ist aber, dass sich leider die leere Miene nicht austauschen lässt.

Classic favorite
This is my favorite purple pen. Which is saying something because I have many purple pens. I grew up with the uniball pens and loved them with all my heart. I’m thrilled I can now get extras in my favorite color so I don’t have to use them sparingly compared to the other colors in the multipack!
