Easy to use and works fast
These whitening pens are incredibly easy to use. You simply open the top, twist the bottom and the gel gets on the brush to run across your teeth. They are so much easier to use than any other teeth whitening product I've tried. I've only used them for a few days so far but can see a difference in my teeth color already. They are something I will absolutely be buying again and working into my daily routine. I also like the fact that they have no annoying aftertaste or smell to them.
