### ⭐⭐⭐⭐⭐ Great pen

My favorite pens on the market. I love the way these write. If you prefer a smooth roller feeling to your pen this may be a bit scratchy for you but they are small, compact, and very long lasting.

### ⭐⭐⭐⭐⭐ When it rains, it shines.
*by T***S on October 15, 2015*

EDIT: I think I figured out my problem. The cheap spiral notebooks from Walmart appear to have low quality paper. Using paper from 150-sheet packs (brighter, whiter paper. Less glossy) results in beautiful, fulfilling script. Updated to 5/5 stars. I'm tempted to -1 star for leaking, but I'll let it be. The picture scorns the product enough in that regard. I really want to like these pens. Moments after using one for the first time it was fading out badly. So I tried another...and another...and so on. Eventually I got to one that worked great. The next day, it was fading, also. So I gave it a little shake and was met with a bubble of ink that popped all over my fingers and the paper I was writing on. Well then...won't do that again.. Three times now I have retrieved a pen from my backpack and met a similar unpleasant surprise. I guess they shake in my backpack when I ride my motorcycle to school. But here's the kicker: when shaken up and bleeding all over the place the ink flows beautifully and I can write with the most consistent, pleasant hooks and curves in cursive script. I wish more than anything they would work like that consistently... I'm going to keep trying because these pens are still much better than the horrid Pentel 0.7mm R.S.V.P , which constantly leak from the tip and bleed through paper. At least uni-ball ink is more forgiving and even smearing a soaking streak of ink across paper doesn't bleed through. I've started using pencil grips in hopes of somehow finding the best of both worlds, no leaking and perfect, consistent ink streams. Alas, my trials have yet to prove successful.
