I purchased one copper tongue cleaner to try, then from a different source purchased a stainless steel one. I had never used a tongue cleaner in my whole 72-years of life and was surprised at how effective they are in not only getting rid of tonsil rocks, but also played a role in helping my sinuses…it goes without mentioning that my oral health benefited! Although I liked both the stainless steel and the copper tongue cleaners, the copper one out and I bought two more to keep in different areas so they’re handy. The copper ones are thinner than the stainless and easier to handle in my weird mouth which has a huge Tora (? Boney growth) and a couple smaller ones which can be difficult to maneuver around. It’s a huge plus that the copper ones come with a just-the-right-size storage bag as opposed to the cardboard slider box for the stainless ones from another reliable company. So now I’m blessed with having 4 tongue cleaners. :) And a cleaner mouth, and much more comfortable breathing. Thank you Wellness.
