Description The Tombow AirPress Ballpoint Pen is designed to be a ?full climate? pen. Each time you push the pen cap on the top, air pressure is injected into the ink cartridge. This special feature enables the pen to write in challenging conditions. For example, it can write upside down or on wet paper. It can also write in lower temperature thanks to the enhanced ink pressure. The pen is produced in a relatively small size, which makes it handy to carry with. The study wire pen clip is also very helpful especially when using it in a working scenario.
