## Description

Uni Power Tank, Pressurized Refill Ballpoint Pen, 0.5mm, Blue body, Blue ink

Review: 普通のボールペンは寝ながら上を向くとインクがでなくなります。 でも、パワータンクはインクの芯内の圧力が高いようで、寝ながら上向きで書いてもインクが出ます！ それに、書き味が良いです。 私はシャーペンよりもボールペンを良く使うので、ボールペンには昔からいろいろなものを試していますが、これが今のところコスパ的にべストですね。 たまたま青色の評価ですが、黒、赤も同様です。
Review: Schone blaue Schrift. Dünn, aber nicht zu dünn. Edel.

## Questions & Answers

**Q: Is this the pen or the refill for the pen? down the page under the heading "what's in the box" it says "ink cartridge.**
A: Pen

**Q: Is the ink waterproof? Can it be used with a waterproof notebook?**
A: Description

Uni Power Tank Pressurized Refill Ballpoint Pen 0.7mm Blue body Blue ink Ink has been pressurized 3000hPa, which allows you to write even the pen is upside down, on a wet paper, temparature -20C degree.

**Q: does this pen write bold**
A: The description plainly says it is 0.7mm, which is what all Medium point pens are, and that's all I use for my main pens. This is a fantastic pen, I've ordered it several times, to be able to lie in bed and write upside down on my bedside notepad, of many things I think of I want to do the next day. However, I believe I recall it being available as a 1.0mm point, which is what most all BOLD tip pens are, or as a 0.5mm Fine point.

**Q: I assume this is a dozen blue pens?**
A: I also assumed this was for a dozen pens.  Received my order today and it was only one pen!  Very disappointed!!!  Will be checking into a return immediately!!!
