Tongue scrapers work as advertised. I bought these for our family of 5 (6 year old is an adult). They're easy enough for kids to use themselves after a demonstration. They are smooth and definitely clean our tongue. Each scraper is individually wrapped. Including travel case. If you're only traveling with one, then that works fine. If you are traveling with more than one, you will need another suitcase. I can put my toothbrush and 1 scraper in the case. I will buy it again if we need a replacement.
