I always face an issue with the color of my teeth due to drinking 5 cups of coffee per day. I have been using this product for a week now and i feel the difference. It is stunning however, while gargling you feel that it is harsh compared to other mouthwashes.
I always had a problem with washing makeup case and have to change it after a while. Actually, cleaning this one is super easy. I bought it from Egypt from Cairo festival city. Its a little bit pricey but worth the investment.
