Review: Amazing and nice looking pens! - I have never loved a pen enough to write a review. I'm obsessed with these! I've tried a lot of gel ink pens and while I have love for my eraseable frixions, for a comfortable nicely designed rollerball this is SO good. It writes very smooth with no skips and I find it very precise - when I write, there isn't any bleed of feathering I sometimes see with gel pens. The barrel is softer so it makes it more comfortable to hold and no smears so far. I definitely wish that there were more ink colors available, so hopefully that is on the way.
Review: Smoooooooth! - Great pens! Smooth writing and a rubbery grip.
