Review (5/5): A teeth whitening pen that actually works!
I purchased this pen on a whim as a stocking stuffer for my teenage son and he loves it. Other teeth whitening pens seem to cover teeth for only a few minutes before getting dissolved completely. But the gel in these pens sticks to your teeth for maximum whitening. It feels like you are getting the staying power of whitening strips with the ease and control of a pen. So glad I purchased this product!
