Uni-Ball One Gel Ink 0.5mm Ballpoint pen 10 Colors Set UMNS05-10C Japan import With Original Stylus Ballpoint Touch Pen......

Wow, I love how colorful depends are even the yellow right its really bright on white paper which is beautiful. I dont love the thickness which I think I just know that I need to get the .07 pens next time. I do love the clip on these, though they clip on my shirt, so easy, and theyre great to fidget with.

Great pins people at my job just keep stealing them :)

I purchased this set of pens twice, the first time in 0.38 and then in 0.5. I am so disappointed in the quality and ability of these pens. They are not smooth to write with at all and when you do manage to write something coherent, it looks as if the pen is running out of ink. When I tried writing with the 0.38 pens and saw this I was like okay maybe 0.38 just isn't my style, it's too thin and too light so I gave the set to a friend. I repurchased 0.5 and had higher hopes but I'm left still disappointed and regretting that I ever purchased these pens. If I could recommend a brand of pen please go with Papermate Inkjoy or Sharpie pens; they are far superior to these.

These pens are not waterproof, but almost worse is that they skip ALOT. You have to press really hard to force them not to skip. Colors are good - but the skipping every other letter makes them intolerable.

I love Japanese pens like these. The design is unique and attractive. The white pen body with the varying color accents makes this pen set look really great. As for the actual writing, the colors all come out reasonably well and look vibrant and saturated. Are they more saturated than "normal" gel pens? I suppose so. If I compare them to other gel pens I've used they do stand out, but you'd have to have them side-by-side to really see the difference. For the most part, I've no problem writing with these pens. Some of the pens however write smoother than others. Whether this a difference in the ink, or just a manufacturer variance - I cannot say. But the majority of the pens I have work well, while the pink and the yellow are the "scratchy" ones and don't write as well as the others. By contrast, the blue, blue-black, and black are the smoothest of the bunch and seem to put down more ink than the others. Note: there is also a version of these pens in a 0.38 tip, and there is a set of 21 as well.
