A miswak is a tooth cleaning stick made from the Salvadora persica tree. It's traditionally used in Pakistan, India, and the Middle East in place of a modern plastic toothbrush. The bristles inside the plant, once exposed by cutting across the stem, are effective as a cleaning instrument. Leen Sadder, a design student, decided to make a modern version:
THIS aims to repackage and promote the miswak as an organic, biodegradable, portable, more beneficial substitute for toothpaste and a toothbrush. The biggest challenge was figuring out how to package and market the twig to a contemporary American audience, who would not be entertained with the idea of biting off the top of the stick in order to use it. The solution for this is a cigar-cutter-like cap that peels off the outer layer to reveal the natural bristles, and slices them off after use. It also protects the stick from germs and microbes.
