Now this looks disgusting and promising. Binotomo Nasu Dentifrice, or Jet Black Toothpaste, expands upon the ideas that 1) adding charcoal powder to beauty products will extract skin impurities and whiten teeth, and 2) once you go black, you'll never go back.
The Japanese tube of black magic combines the cleansing properties of charcoal with the salty allure of Japanese eggplant. Yes, that's right. In addition to looking like the color of rotten teeth, Jet Black Toothpaste also tastes like a pickled vegetable. Bonus #2: it will also stain your clothes! All in the name of super whiteness from super blackness.
Jet Black Toothpaste comes in packs of 2 in case you want to share some with your chain-smoking, coffee-guzzling oral horror of a friend. Additional teeth cleaning ingredients include water, sea salt, menthol, glycerin, kaolin, calcium carbonate, and Xylitol. If the toothpaste causes skin or gum irritation, its makers suggest seeking a dental specialist and scheduling a denture fitting.
