show those pearly whites [SEP] disclaimer i was chosen to review this product at a discounted price in exchange for my honest opinioni decided to try the teeth whitening strips since i am a heavy coffee and tea drinker although i go to the dentist every months i wanted to try and combat the coffee staining with the whitening strips as a extra backup everything came well packaged there were pouches in the box that you open by pulling the tab these have a slight after taste that was not bad at all it did not taste too much like medicine but more of a mint flavored toothpaste i simply applied to strips and watched one of my favorite shows and by the time it was over then it was time to remove the strips the strips were easy to apply and stayed on until i removed them my teeth look lighter and there was no gum or teeth sensitivity
