uni Power Tank, Pressurized Refill Ballpoint Pen, 0.5mm, Red body, Red ink

Great pen, it really writes upside down and sideways. I have been using it for months and I have to say that it’s the most reliable pen I’ve ever owned.

This pen does right while upside down as advertised, but it is a very fine point so fine that it is difficult to see. I got it to write on my calendar that is hanging on my wall at the point is so fine it’s hard for me to see what I wrote.

Super fine point but very "scratchy" feeling to it. So fine you can hardly see the writing. But yes, it will write even upside down.

Powertank pens are great the ink doesn't bleed through the paper and it can't be washed off-no check forgery! Smooth writing and no skipping too.

I love the way it writes

Works great in car in cold wisconsin winters

Let me start by saying that I'm not a fan of ballpoint pens. This one is no exception. It writes very scratchy and skips. I prefer a fountain pen. This pen has not changed my mind one bit. It feels stiff. I feel like I'm dragging something hard across the paper. Like a nail would be the best way to describe it. I was hoping a pressurized pen would be better than a normal pen. It is not.On the bright side. It does write upside down.Over all, not a good writing experience.

Love the product
