Years ago, while working as design manager in one of quite re-known US toy companies I met with inventor from UK, who invented ingenious device - "Blo-Pen". His name is Terence Bolton. His personality and his work inspired me to create a series of similar products for kids. Major difference is that I dislike using markers as source of inks for spraying as I have never seen markers produce stable uniform and high quality spraying patterns. I like using liquid inks for my spraying devices. So, I dessigned several versions of my own blow-pens, that is, airbrushes which use air from user's mouth for spraying.
