Review on AsaVea Teeth Whitening Pen - 2 Pens, Over 20 Uses, Highly Effective, Painless, Sensitivity-Free, Travel-Friendly, Easy-to-Use, Achieve Beautiful White Smile, Natural Mint Flavor by Sandra Saksena

I'm so glad I found them! I'll probably use them forever, no kidding. I usually use whitening strips, which is a frustrating process as they hurt, feel weird, and have to stay on the skin for an hour or two at a time. When I saw these pens as an alternative to strips I wasn't sure they would work because they seemed too good to be true. But they work! I think they should contain a milder, more diluted bleach than the strips I've used because they don't hurt at all. They whiten my teeth more slowly and gradually than the strips, but I'm totally fine with that as I prefer to take my time with the whitening process and avoid the pain caused by the strips. As a bonus, using them is actually a very pleasant experience. You are basically painting your teeth. This is funny! It has become a really enjoyable part of my daily life.
