These pens just didn't do it for me.
I bought these pens as they are the only pens I found with such a fine tip. I was very optimist of this product when I saw the reviews, but I was very disappointed.

Writing Harmonics with Uni-Ball Onyx
Uni-Ball Onyx Rollerball pen protects the paper from leaks. It possesses strength with no breaks in letter formation whether it be cursive manuscript or calligraphy. What can I say - it's a beautiful writing experience!

Very nice fine print!
I love this pen. Its fine print. No bleed through like other pens! Would totally repurchase again. It makes a big difference in the writing. My writing looks so much neater and nicer comparing to a 1.0mm pens.

Pen for all seasons.
I have used these pens for years including in cold Alberta winters and the middle of Africa at 40C. They work well and my handwriting looks good.

Love them!
These "Onyx Rollerball 0.5mm Blue" have been "my pens" for years now. I keep one in my pocket at all times. The quality of the writing is excellent and they feel smooth as they write.

love the smoothness
I love how easy it is to write with these! the ink is perfect and it comes out so easy that I don't have to press hard. The only downfall is sometimes I have to hold up so the ink gets to the point but that's pretty much with any pen :)
