I was able to practice on my younger sister and her friends for New Year’s which is what I was hoping for and their tooth gems are still on their teeth nice and strong. I practiced on myself and was able to pick a gem off with my nail (which is good as some people only want them for a party or short-term) but the others that I have left alone have stayed on. I brush my teeth 3 times daily with an electric tooth brush too, and I visited my dentist yesterday and he said they looked well-done! Thank you very much for your product and excellent customer service.
