Uni-ball SXR-7 Jetstream Ballpoint Pen Refill - 0.7 mm - Blue

all the other reviews make this pen refill seem horrible.... well this is a huge understatement for this refill. i recently bought a jet stream with this refill and after i was out of my first refill, i popped this guy in there. like every uni pen, this refill glided beautifully across the paper and made my writing appear crisp and clear. i love this refill and intend to buy many more for my pen. I recommend this refill for a lover of beautiful writing...

I liked the black ink that came with the original 0.7 mm pen, so I thought it would be nice to try out the blue ink. It wasn't as good as the black ink. I immediately thought that I got a defective one, so I ordered another Blue Pen refill, but that one was just as bad as the first one. It was "skippy" at first. Then after 2 pages of writing, I was just scratching the paper with a piece of metal because the ink wasn't coming out. It felt like it was out of ink, which was impossible because I can still see the ink in the cartridge. Plus, the original black ink that I had lasted until all the ink in the cartridge was gone. I left it alone for a few days, and decided to use it again because I don't want it to go to waste. It was a bit better. It "regained" some ink so that I could write again, and it wasn't as "skippy" as the first time. Overall, it wasn't as smooth as the original black ink.

I love this pen!
