UB-150 Eye Micro Rollerball Pens, Blue Uni Super Ink, .5mm Nib, Box of 12

I've used these pens now for years, I have a nice Parker pen that's been gathering dust because these are just perfect. Lovely vibrant ink that really stands out, is very permanent on paper and the pens last a long time (a year in my hands in regular usage). I'm a leftie, so ink pens have always been the bane of my life, however the ink on these pens dries very quickly and doesn't smudge so they're absolutely perfect to get that high quality ink look and feel (biros just feel cheap especially on important documents) at a very good price. As soon as this pack runs out I will instantly buy another and will continue to use these pens until they stop producing them.

These are great pens! I've been using these pens for a long time and they are just perfect. They have never leaked and the nib is very smooth. I got the black ink version and the ink is a nice deep black - great for writing or drawing. The ink is also waterproof so can be used with confidence for example for addresses and will not wash off in the rain! I previously used the UB150 which have a finer nib but I found that size a bit scratchy on some papers. These are also great value for this multipack. Recommended.

Excellent pen with a premier nib. Good for writing in exams (even as someone who has the misfortune of being left handed). Strong line and easy to write with. Only problem is that it can be uncomfortable to hold after long periods. Which is not ideal. Additionally it is impossible to swap out the ink after the contents have ran out however this is not a problem as the pens do last for long periods of time with heavy use. Good Product.

This is my pen of choice. Smooth, clear , even writing and long-lasting. Simple design with excellent ergonomics. A pleasure to use. This pack offered the best price that I could find for the genuine, original product. Cheaper counterfeits are available.

My left handed daughter finds these pens much easier to use,they are comfortable to hold,the ink dries very quickly.it is easy to see when the ink is running low so as to know when to order replacements.Good quality,multi-pack well priced.

These are the best roller balls I have used. Nice to write with, and they press on untill the ink is all gone. I'm tempted to try refilling them as the ball is that good (but I won't.) The UB-150 is a bit finer and better for tiny writing on newsprint (yes, I do the puzzle) but these are better for everything else.

These pens help produce some very neat writing, and are good for when you have a lot to write, as the rollerball really helps with fatigue. Kids aren't used to writing these days, with everything seemingly being typed and printed. However, some of us dinosaurs prefer the traditional methods, and these pens are just the job! Top marks for top pens! 5/5

Lovely pens, I've had many packs over the years. They give a lovely solid colour (once dried) and write perfectly until they're totally empty. Black, Red and Blue all give lovely solid rich colours. However, for a thinner tip try out the UB150 - I've tried them both and prefer this thinner tip as I can write smaller and the ink should last longer as well.
