Thank you @crest for this wonderful gift!😍🦷 These are their 3D white strips. It’s a dental whitening kit that provides professional effects. It can make your teeth 18 levels wider. It removes over 15 years of stains and only three days. Use at once per day and keep it on for 45 minutes. Each treatment comes with two strips, one for your upper teeth and another for your lower teeth. They are made of a nonslip technology and peroxide layer to provide a comfortable whitening experience. I have used crest whitening strips for many years and have gotten amazing results and feedback. I definitely recommend them, although they are pricey. However, I use them in moderation as using it too often can cause teeth sensitivity. I believe they are worth the investment as they last a long time. I was able to get this box for free by joining a zoom call!
