Over the years, I have reviewed all of the Uni-ball Power Tank pens that I could get my hands on: the Original, the Smart Series, and the Smart Series High Grade. I had no idea there was an Eco version until my friend Carmen brought one back from Spain and sent it my way.
My first reaction: Wow, that is one ugly pen!
I understand that Uni is going for the eco-friendly look but I’m not sure they pulled it off here. It actually doesn’t look so bad in the picture, but in person it comes off as odd. The brown grip area is what gets me. It is lighter than the brown plastic clip, and grip wear shows up even lighter. That makes for a worn down looking grip before it has had much use.
While it may not win any beauty contests, it is still a decent pen. The blue 1.0 mm pressurized ink cartridge is smooth and dark. The line does have a good amount of white space in it, which is a flaw seen in many ballpoints. I have had more success writing with the 0.7 mm Power Tanks, so that would be my preferred Eco option as well.
The Power Tank line is a great choice if you are looking for a pressurized ballpoint pen. Just know that there are several barrel options, ink sizes, and ink colors to choose from.
