Lena uses the Smile lab FLASH strips to keep her teeth white. She really likes the package:
It is both cute and convenient to carry around if you want to take some strips with you on a possible trip. They work quickly, so if you are going somewhere special and want whiter teeth in no time, this is the product. You just need to put them on for 15-20 minutes, and they will already be much whiter! 🙂
