LOVE these!
Love love love these pens. They are super bold and write like butter. I am a nurse and we at my work, we love our pens. We are constantly comparing pens and looking for bold, nice gliding pens. These are perfect! They do smudge a little but it is only random - doesn’t happen all the time.

My very favorite ink pen in the whole world
These ink pens are my favorite ink pens to use. I never had a problem with ink flow. It is smooth and reliable. They are fun to use. You do have to wait for them to dry before it smears but not long. The pens last for a long time and you can buy refills for them. I love the bold thick lines. Excellent value for your money.

Bold gel ink line, looks professional.
Very smooth writing and heavy bold ink deployment. If you want a very bold gel line with smooth flow over the paper, this is the pen for you. The 1.0 bold is actually very bold and thick, it can be a bit smeary on slippery paper but after a few seconds it's fine. The style is also very nice and elevates this pen to look more professional. The body of the pen is a bit thick, however the rubber grip does not catch on things like when being put into a shirt pocket. I use this for my work pen where I need to reference what I write in a dark environment and the bold ink really stands out. The pen looks professional at the same time. I do wish it was slightly less expensive as they run out fairly quickly because of the bold gel ink. But overall I highly recommend these if you need a bold line and a professional looking pen.

Favorite pen
I LOVE THIS PEN! The grip is perfect ,it is really comfortable ,I can use this for a long time and not get any hand cramps. I also like that it can take a lot of different brands of refills. The ink in the pen is really think and juicy but it does take a little bit to dry or it will smear.

Bold black ink, quality pen
I saw these pens on a Tik Tok and just had to try them. They did not disappoint! I am a pen connoisseur and I fell in love with this one from moment one. Love writing with a thicker pen, you will love this one. Buying a second pack for school. Every one at my current job says, nice pen when they use it to sign their credit receipt.

The BEST.
I’ve been a Uniball fan for years now and the Signo 207 was my go to, but now THESE are my favorite pens. What is better? The thickness of the pen. The big metal tube is perfect in your hand, the rubber grip is perfectly placed and the clicker is even better with a nice flat top to it. Same great bold 1.0mm quick drying ink as the Signo 207. Marked Japan. Can’t ask for any more. You made the perfect pen Uniball.

Would've given it a 5 star but it smudges really bad. Takes at least 10-15 seconds to dry. Ink is bold and smooth to write with. Barrel is wide and comfortable. Wouldn't recommend to lefties.
