It's a good buy if you enjoy a well made everyday pen.
I took advantage of the discount, received my order in a day and was happy to find the pens and ink are made in Japan. The box was a bit crunched up and I need to check all the pens to make sure the tips are all sealed and new, but the one I pulled out to test was sealed and wrote smoothly. No smears/smudges, clear black ink, well made and has a sturdy metal clip. I unscrewed the barrel to take a look inside. The ink barrel visually shows quite a bit of ink in the cartridge, so no short cuts there - should last awhile. Ink flow is clear and not blotchy. The muted colors are a nice touch and the tactile area where you hold the pen is smooth while providing grip. It's a well thought out and elegant design. I need to grab a few more boxes while the price is still at about $1/pen. I recommend this product wherever you can get it. Wish: I wish the ink color came in indigo.

Favorite Uniball pen!
Probably my favorite pen from Uniball, super smooth, the clickyness is very satisfying, ink comes through very well and I haven't had it ever be 'dry' (where you have to scribble on the paper to get it to 'activate'). The clip can be pressed down from the top and it's both fun to fidget with, and also very practical. Really good! The colors are very nice too.

Worth the money!
These pens are the best pens I have used. I dont have the fatigue that I normally get when writing with other pens all day with my hands. They write smooth and dont smear. I tend to lose them when clients come in as they love them as much as I do once they use them.

Great daily drivers
Absolutely love the pens, they are thicker in writing but extremely smooth. The ink flow is great, the colors and mechanics are fantastic. They’re light but durable and a great value for money.

Works well.
Once initial protection cover is removed from the pen point, it writes smoothly.

Great for journaling!
These are great for journaling! The pen doesn’t have a cap I will lose, and it has a clip to hang on to my journal. I love the aloft feel of the barrel and smooth ink.
