You will receive: Four surgical grade stainless steel tongue scrapers, four color handles allow you to better distinguish with your family, we will also send you four carrying cases for you to carry better during travel. What it can do for you: If you have had bad breath for several years, but don't know what caused it. Used a brush, used dental floss more and more, but none of these worked. Before using a tongue scraper, you can't imagine how dirty our tongue is. However, we know why we have bad breath and always feel that food is tasteless. The scraper is super easy to use and can remove all the dirt on the entire tongue, leaving your taste sense wise. Cheers to waking up without terrible morning bad breath and enjoying every meal. Double-sided design: Some other stainless steel tongue scrapers work well, but they have a metallic taste, which is a bit offensive. We use odorless stainless steel, which will not cause nausea (if you have slight nausea when cleaning the root of the tongue, extend your tongue as much as possible). The tongue coating is sensitive when you use it for the first time. The tongue coating cleaner adopts mirror polishing, the surface is smooth, and it will not cause any damage to the tongue coating. And they are easy to clean. After each use, please rinse with water and put it in the brush cup. But if it is the first time to use, please wash it with boiling water or salt water, and wash it at least once every three months.
