“I've been using this pen right after my lunch at work. Great idea, but haven't noticed too much of a difference in the colour of my teeth. Maybe it just needs more time.”
“Hi guys definitely a keeper.....Well worth the money and does work wonders on stains and marks. I was a smoker for years and I know it will never be perfect but definitely worked well on whitening. Bought the pen to use to top up and using the toothpaste all the time. LOVE IT !!!!CANT RECOMMEND THIS PRODUCT HIGHLY ENOUGH.”
