Uni-ball Deluxe Rollerball Pen, 12 Blue 0.7mm, Smooth Writing, Waterproof Ink, Fine Point, Office Supplies

I've been buying and using these pens for at least 12 years now, other than fountain pens I'll never use anything else. The black is dark and maintains a dark color with no smudges or smearing but the blue just pops and is quite vibrant so it's my usual every day carry pen.Two cautions, make sure the cap is on tight before putting in a pocket, if the rollerball contacts anything it will start dispensing ink immediately and it's nearly impossible to get the ink out of most fabrics (I ruined a dress shirt and a cotton undershirt because I didn't get one pen fully capped, it took a couple scrubs to get the ink off my skin, it's that durable and I also had one discharge in a briefcase, I still have a stain on the inside) and second caution, these pens are so smooth and good that people WILL try to steal them from you every chance they get. I only take one at a time to work after I kept a box at work and noticed them slowly disappearing. They're THAT good.

I'm somewhat a pen snob and I was highly surprised by this pen. It writes beautifully and does not clump or bleed through. Also, it glides over the paper with little effort. Buy them!!!

Clean and professional looking. Best part is that it clips to your shirt pocket for easy and quick access. Also it is upside down and does not leak into your shirt pocket. Can't tell you how many shirts I had to throw away from leaking pens costing so much more. No longer a problem. Please never stop making these or let me know if that becomes a plan and I will stock up. Width on the write is "fine". It is not like the black covered Uniball pens that have a medium width. Very smooth to write with.

I found out about these from seeing Bill Gates in a documentary holding one of these up to his mouth. I think Gates used the ultra fine or extra fine, but it was definitely an archival quality uni-ball Deluxe. I used these for years for business and journaling. I use the blue so I can differentiate originals from B&W photocopies. Lately, and I do not know if this is because I am applying too little or too much pressure, but every two or three words I have to go over a line again in order to get the ink to come out of the pen. I switched to an archival quality purple art pen. I am giving these four out of five stars because maybe I just got a bad batch. A year ago I would have given these five stars. These served me well for years.

Had to buy these cuz I one I’ve been using since the nineties finally ran out of ink. That pen lasted thirty years. I know you don’t believe me but it’s true. Buy them and find out for yourself.

I’ve been using Uni-Ball since middle school. This pen is fantastic value for money. I do most of my work note-taking with it.

Received repackaged box containing only 11 pens which all had individual upc codes on them. Unlike previous purchases of same pens

I first got one of these at a meeting. I liked using it so much that I searched the internet to get a replacement when it was running out of ink. The tip flows easily on paper with a nice blue color. The barrel is perfectly sized for my hand--not too skinny and slippery or too big. My hands tend to be cold all the time and skinny pens are hard to manage.
