Air Writing:
The specially formulated compression ballpoint pen ink allows compressed air to be pushed out at all times, so you can write on wet paper, below freezing or upward.
In addition, the micro-protrusion on the spike ball surface of the nib writes ink and grips the paper firmly so you can write on smooth paper surfaces such as photos, drawings and more.
