Review: 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 desertcart 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.
Review: 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.
