Just a simple tongue scraper but the only one I can find made with stainless steel. I’ve had same one for 8 years, as it refuses to break. Easy to clean and gets all debris off my tongue in a couple of quick sweeps.
[I have not used this particular tongue cleaner, but I am a tongue scraper convert. They improve the bad taste I have in the morning, especially after eating onions the night before. -- Mark]
