Review: NYT Wirecutter rated it high. For good reason. It is well made and looks good. Oh, by the way, it writes very well. desertcart’s price is reasonable.
Review: Jetstream pens are the best pens I’ve ever used. They dry nearly instantly and the ink is water resistant when it dries. These qualities are important to me because I’m a leftie and I like to highlight often. They also write very fluidly until the last drop of ink. Remarkable pens. Wish they came in more colors.

### ⭐⭐⭐⭐⭐ Review
*by A***. on 12 June 2021*

I don't know why so many people reported in the past that they didn't receive the full amount; I just wanted to confirm that I had no issues with my order (April 2021). I received a full box of 12 Uni-ball Jetstream RT 0.7 pens. And yes, needless to say, these are the best pens. You should read the full review by the NYT Wirecutter (Google it), they explain in detail their methodology and how/why they concluded that this is indeed the best pen. Quote from that article: "Its pigment-darkened ballpoint ink flows out smoothly and evenly, without skipping and with minimal pressure. The ink sinks into paper and dries quickly (which is great for lefties)".
