Well, this little device claims to be able to reduce your bad breath. This disc of stainless steel relies on the story that chefs often use stainless steel to remove fish odors and the like from their hands. Apparently the bad odors stick to certain metals in the stainless steel.
Would you like to shove a cold little disc in your mouth, well we’ll see. Remember, though, that most bad breath comes from your lungs after a meal with lots of garlic or onions. This won’t help that.
But with its small size it might be an alternative for those that can’t get hold of a toothbrush when they are out and about, or if you just like to try little gadgets.
