Uniball Signo DX 0.38
I have developed a gout-like arthritis in the right palm of my hand in the section where the palm meets the thumb. This is the hand I write with. I wanted a pen that felt good in my hand and was easy to write with. So this time I got on Amazon and read reviews for at least half the day, and after reading all those reviews on different pens, I liked the reviews on this pen, and I bought quite a lot of them. I am absolutely delighted with this pen. It is made out of thick plastic, making it very sturdy and long-lasting. Plus the weight of the pen, along with the easy rolling ball to write with, makes it effortless to write with. I don’t even have to put pressure on the pen in order to write. The pens are a little pricey, but are worth every penny. The ink cartridges are changeable after running out of ink. That’s another thing I like about this pen....easier on the environment with less waste. As a rollerball tip, the 0.38 is an excellent width of ink line for my writing. It now so much easier to write like a pro. I have found a pen for life. The best pens I ever owned. I just pray that Uniball never stops making these pens, and will always continue making them just as they are, with high quality materials for a wonderful writing experience. Honestly the best pens I ever owned in my 70 years of life.

Best pen ever…
It’s so smooth and no ink leak out or smear it. This is not the first time I used these pens. Because it’s so good, I stick with this brand and reordering when I need them.

Best Pens EVER!
I love these pens. It is literally my favorite pens now. You should definitely buy these pens. They are especially good for left handed writers.

Great Pen
Great pen, Love the fine point. They work as expected. It's a smooth writer, the ink is a nice dark black, and the body is well made. Nothing moves when you write. The ink dries fast enough for me but I'm not a lefty. The refills seem great as well, though I haven't opened them. My only issue is not with the product but with the seller. I received 4 pens and 5 refills not 5 pens and 5 refills like I expected. A slight issue but a bit disappointing.

Too scratchy. Line too thin. Not a fan.
As soon as I opened this pack and tried one, I regretted my decision. Bought this based on some dude who has a blog and is a supposed pen connoisseur, who said it's his favorite pen, hands down. I fine it scratchy. The line is razor thin. It doesn't flow very well. It makes my hand-writing look like I'm a stroke victim. Not a fan. Now I'm stuck with 10 of these things. I pawned a pen off onto each of my kids and one for my wife. 7 more to go!

THESE ARE NIKT WATERPROOF
All info says they are waterproof. They are not. I’ve ruined some art work and I’m must sick about it. I always use another brand...I just wasted my money on theses pens.
