‘on air’ was conceived by frequent toothbrush-carrier noaa eshel for israeli company, monkey business. during conceptualization, various versions of iconic vintage microphones were examined. a rectangular streamline microphone was chosen, aside from aesthetics, to accommodate thousands of toothbrushes.


eshel researched toothbrush sizes and shapes, and tested countless ways to hold the brush in place. after many mockups, a final shape and proportion were chosen and ‘on air’ was born. the cover is made of plastic, but don’t let that deter from rehearsing your friday night karaoke routine.
