Review on 🦷 Crest 3D No Slip Whitestrips Professional Effects Teeth Whitening Kit - 20 Count by Hongseok Bak ᠌

I went through a 20-day whitening course, I am very pleased with the result. My teeth have always been yellowish, but now they are really white! Even the crown, which I put in the color of my teeth, is now completely inappropriate) but you can clearly see how it was "before" and how it is now) The only negative is the sensitivity of the teeth (and they have always been sensitive for me). But it goes away as soon as you stop using the strips.
