uni-ballPower Tank Retractable Ballpoint Pen, 1.0mm, Colour: Black (Single)

I work outdoors & this pen is great for writing in wet conditions or at funny angles etc so the pen is a good all rounder & lasts all the way until the ink runs out so would definitely use time & time again.

Positive: better red colour than fisher space pen red cartridges, even writes on glass, very smooth on paper, cheap, reliable, refillable, works all the time, great for correcting or writing formulas, writes on wet paper and skin, very nice 'clicking sound', works fine underwater and won't smear. I have medium-sized hands so they are a little bit too thick for me because of the rubber grip but still comfortable to hold and write with. Also they don't leak on airplanes or in hot temperatures. I used standard A4 paper and rite in the rain notebooks, pen performs great on both, the only time it would smear is when you apply quite a lot of rubbing alcohol on the ink.Negative: I wish they would come in a 12-pack.

I too use these for doing crosswords in bed, in fact mainly for writing out anagrams as the XW is on a tablet. They work perfectly upside down and I wouldn't be without one. Given their sole use, they last over a year. I bought one in 3/14, another in 11/15, two more in 5/16, some refills in 4/18 which I only used once, and (forgetting I still had refills) have just bought two more pens. The refills therefore seem to last longer than the pens.

Great for doing my puzzles and great price

I buy these for work (I’m a chef) because of the pressurised ink cartridge they write upside. They are comfortable to use and last ages.

Okay so I wanted a refillable pen as I was going to need one and the cheapest one I could find was 5 pounds but this one was cheaper and was by a company that I knew so I decided to buy it and it was an amazing purchase. I'd highly recommend this to anyone.

I bought these for one feature - they can still write whilst being held upside down, so they're good for writing on a notice board mounted on a wall. They are also pretty nice pens to use normally too. The gel is even and they don't blob.

Comfortable to use, really does work at any angle, writes on wet paper and waterproof paper. Bought for my son who is doing basic training and he says they are great, and haven’t let him down, even on exercise in the pouring rain. He hasn’t found an instance where these pens don’t perform as expected. I am happy to recommend these pens and I would definitely buy them again.

Pen works as expected. Bought this pen to leave in my car in the cold and not explode on hot days. Haven't tested it yet but I believe it will work as expected (if not, I will update this).The reason for one star off is that the product description says this pen is 0.4mm, but as you can see in the image, it is actually 1.0mm. A bit misleading, but if you don't really care about how fine it is like me, then this pen will work for you.

Schreibt auf nahezu allen Papieren.... Egal ob nass oder trocken! Super

A Uni Powertank é leve com boas dimensões para transportar para todo o lado, num bolso ou numa mala. Escreve de forma fluída tornando a escrita agradável. Talvez um pouco mais grossa que outras canetas mas rapidamente nos habituamos á sua espessura. A comprar desde que a apanhem com preço razoável entre os 4 e os 6 euros.
