uniball Air Porous Point Pens, Medium Point (0.7mm), Black, 12 Pack

these used to be my holy grail pens until i discovered the pilot v10 1.0. i've been using these pens for about 5 years now, and they were always the first one i'd grab when i needed a pen. my husband would always steal them from me. the ink is so smooth, dense, and juicy. if you're a lefty i would probably not recommend it, as it takes a minute to dry, but i've never had an issue with the ink smearing. it also doesn't bleed through paper. they seem to last forever before running out of ink. i have purchased maybe 2-3 packs in the last 5 years and that's mainly because i lose them...or someone in my family steals them lol. the only thing i don't like about these pens is the removable lid. i wish the tip was retractable. although i have a new holy grail, these will always be in my top 5. GET PENS!! hopefully uniball doesn't ever discontinue them bc then i will have an existential crisis.

These are really nice bold gel pens! I love anything by Uniball brand, and these are amazing. They write very smoothly and don't skip. I would highly suggest these! I love the dark ink and no-bleed thru.

I bought these specifically so that I could refill them with waterproof fountain pen ink for sketching, and for a special ink I use at work to write on leather with. I'm primarily a fountain pen user, which has really emboldened me to demand more from other writing utensils--especially in being eco-friendly. There is absolutely no need for disposable plastic pens anymore, except for the fact that companies make it difficult if not impossible to refill the pens. These are super sturdy, the roller ball writes amazingly well at almost any angle, and better yet, they are easy to disassemble and the cartridge inside is perfect for refilling from bottled ink! My only regret is that the box of 12 I bought will probably last me 20-30 years. I'm not even joking. I've even given several away to family members and taken some to work to leave about with explicit instructions to get them back to me when they're empty. I really hope Uni-ball continues to make these pens, and I will recommend them to everyone. It would be even more fantastic if a big company like Uni-ball came out with a product like these pens sold with a bottle of ink (their own if they like), easy instructions, and specifically marketed them as an environmentally conscious pen product. The more "mainstream" refilling pens becomes the better for the planet!

Writes nice and dark. No issues with it freezing up or stopping

This is my favorite pen for sketching. Normally I would rate it five stars, but two out of the 12 pens in the box I bought are slightly defective. The ink flow skips and the line is very thin when you hold the pen completely perpendicular to the paper. They write fine when you hold the pen out of 45° angle to the page. The other 10 pens in the box do not have this problem. I have been buying this pen for years in packs of two or three, and have never had the issue before. I would return this box except that I got such a good price ($8.09/12) it's worth keeping them.

Great pens!

Awful. All pens were skipping ink right out of the box. I would give these pens 0 stars. Ink flow is so uneven and ugly. Probably worst pen I've ever purchased lol. Uniball 207 plus are waaaaayyyy better.

IMPORTANT NOTE: There are listings for the uni-ball air indicating fine (.5 tip) and bold (.7 tip) but there is only one tip for the air pen produced by uni-ball, which is the bold .7 tip. However, as the uni-ball website indicates, the line can vary from .35 to .7, depending upon pressure. I tend to use heavy pressure when writing, and get a consistent, bold line. PROS: *bold tip *secure cap *comfortable *affordable *smooth *consistent *non-smearing CONS *bleeds through checks *ink levels not visible *limited color range *black ink is not a deep black
