✅What You Will Receive: Four surgical level stainless steel tongue scraper, four-color handles allow you to make a better distinction with your family, we will also send you four carrying cases to carry better in your travels. ✅It Can Do What for You: If you had bad breath for several years, but didn’t know what causes it. Use brush, floss more and more, but none of that ever worked. You can't imagine how dirty our tongue was until using the tongue scraper. However, we know that why we have bad breaths and always feel food tasteless. The scrapers are super easy to use and get the entire tongue clean of all your grossness, make your taste sensible. Cheers to waking up without horrid morning breath, enjoy every meal. ✅Double-Sided Design: Some other stainless steel tongue scrapers work great, but they have a metallic taste, that is kinda offputting. We use odorless stainless steel, which will not cause nausea (If there is slight nausea when cleaning the tongue root, please extend the tongue as long as possible). When you first use it, the tongue coating is sensitive. We can use the A-side to scrape 3-5 times (refer to picture 6), and then change to the B-side.
