Best ones to buy!
I think this is ny 3rd review of these.  They are the only ones I buy. They adhere well, are easy to use and you can see the difference immediately after.<br />My teeth are fairly white so I use them to keep the coffee and red wine from sticking. I love this black licorice that I get from our local co-op and it makes my teeth black! So I definitely need to use a set after a few days of eating licorice. Sometimes I'll use one daily.<br />Certainly the best!
