I use these for my mixed media paintings
I use these in the standard way I always do—mainly for final line work in my watercolor and mixed media paintings. The fine line is clean and consistent, and the ink holds up well over paint without bleeding. Solid pen that does exactly what I need.

I enjoy the smooth glide of the pen's tip across paper.
I believe these pens have improved my penmanship and writing with them is quite enjoyable whether you like writing letters or grocery lists.

Best pens ever
Thin tip, phenomenal quality. These are my favorite pens, but if you're taking very intricate notes it can be difficult to read pages when they're back to back.

Same as Vision?
Updated review on day three: I used the first pen at work and wrote the review below. The next day the pen started leaking from a crap under the little blue cap at the bottom of the pen. I popped that cap off to check and sure enough there was tiny crack leaking ink. In like thirty years of using Vision pens I've never had this happen before. My assumption is that these are a cheaper/crappier version of the Vision. But, perhaps I'm wrong and this was a fluke. I'm now using the second pen and will update this review if the second or the third leak as well. On a positive note, the ink does wash off your hands with soap and water. Not sure about clothes though. Original review on day one: I've been using Uniball Vision pens for like thirty years and I love them. So when I saw these were supposedly roughly the same pens for cheaper, I decided to give it a try. They are, from what I can tell, the same. They write the same, feel the same, etcetera. I googled the difference and supposedly the ink is slightly different chemically or something but who cares about that... They work just as well as Vision for cheaper so I'll continue to buy them.

Quick response, excellent product
This pen writes a nice line that is a little thicker than expected for a .5. It is excellent for signatures.

These are my favorite pens, in blue. This is the best ink and tip for writing comfort and depth of color. It's easy to read, and glides smoothly on the paper. They're a little thinner tip than the black ones I usually get, but I got used to it. I basically refuse to use anything but these and the black ones of this brand.

Mentre il colore e la fluidità dell'inchiostro erano decenti, ho notato che la penna tendeva a sporcare la mia mano mentre scrivevo. Una delle cose più fastidiose è stata che l'inchiostro sembrava non asciugare abbastanza velocemente, il che ha portato a macchiare la mia mano durante la scrittura. Questo problema è particolarmente fastidioso, specialmente se si sta prendendo appunti o scrivendo in modo continuo per un periodo prolungato. Ho finito per dover essere molto attenta a come tenevo la penna per evitare che l'inchiostro si trasferisse sulla mia mano, il che ha reso l'esperienza di scrittura meno piacevole.Tuttavia, non tutto è negativo. La penna gel aveva una scrittura fluida e scorrevole, il che ho apprezzato. La tonalità di blu era piacevole da vedere sulla pagina, e la penna aveva un buon controllo. Ma purtroppo, il problema della macchia sulla mano ha messo un po' in ombra queste qualità positive.
