Uni-ball Power Tank Ballpoint Retractable & Fine Ballpoint Pen Rubber Grip Type-0.7mm-black Ink-value Set of 10

Been looking for these for years--thank goodness for Amazon; because, I don't think they are available in stores anymore (at least none that I have seen). Wonderful ability to write upside down, under wet conditions and permanantly without smudging or smearing! Rubber grip is nice and is very durable! Wish it came in "wider version" for larger hands; but, "grip" is good. Also, didn't realize they were "fine point" when ordered; however, the "ink spread" was good and did not "skip" during "rapid writing" so was maybe a "positive" mistake as it "writes just as well and with a thinner line!" Nice "bulk" package, too, so I am "never without a good quality pen!"

The pen is amazing. The best part is writing in any angle and upside down. It had a decent weight. The pen ink flows very liberally, despite the small tip. Definitely my go-to every time.

These are fairly ordinary pens in appearance and feel, but for an extremely reasonable price add the significant advantage of being under pressure internally so they continue to write in harsh environments, including heat, cold, water, and upside-down.If you work even partially outdoors, ranging from field engineer to delivery driver, these are an extraordinary convenience.

Nice solid built pens. This is the first set of Uni-Ball pens I've purchased and so far I am very pleased. The clicker works fine so far and the writing is smooth. No build up or mess. The rubber grip is okay, does what it's suppose too...The 0.7 is solid. I like that it is true and not too thick or fine. I took a chance going to the Tank series and I'm glad I did.

These pens will not die in your vehicle outside in the heat or cold. They only stop working when they are out of ink. And I mean almost every drop. I never want to use another type of pen again. These also come at a great price for what they are.

Fantastic pens. I bought these as gifts for professionals that work outdoors in rain and New England winter climate and these pens perform as well, if not better than a very notable comparable brand that charges much more for their pens. These also have a huge reserve of ink! Mine has run flawless for nearly a year now - amazing I haven't lost it but at their price I can afford to. Highly recommend these pens. Thanks for reading.Spring 2015 update. These pens are as good as any Space type out there and hold way more ink. My crew has had them in use for years without issue (other than loosing them). Strongly recommend to buy if you need durable ink. Thanks for reading.

I work in a gmp facility and these are the only pens that respond 100% of the time and give me no entry errors on my paperwork. Write on anything in any direction. I bought them for my entire team. Best pens I've ever used!

Great pens however I don't think they are actually 0.7mm. I compared them to my Fisher 0.7mm and my Foray 0.7mm pens and the tip looks smaller and the ink line is definitely thinner. I think they're closer to 0.5mm. So if your expecting that normal heavy boldness of a 0.7mm tip you will be a little disappointed with these guys. Other than that, they're great pens and would have gotten 5 stars.
