works well durable good value [SEP] i started using a tongue scraper a few years ago after receiving a plastic one in a kit from my dentist these stainless steel scrapers are much more durable and they work well although a little narrow for a full sized adult mouth however i was able to carefully bend one to a slightly bigger radius so it is more comfortable for me to use and at for a pack i could share with my spouse and child and still have a spare i do not know if these are really surgical grade stainless but they are non magnetic so not made of cheap steel i would buy more if i ever had the need but i doubt that the first set will ever wear out
