This pen is effective and so convenient just to swipe on my teeth. I prefer the pen over gel I have to put on with a little spatula tool. The ingredients and the mint one I got is pleasant and I'm a repeat customer

This product works for us. We love it so much and really reasonable price for making a beautiful teeth and it made us more confident to smile and saving $$

. Works as advertised. Only a 4 instead of 5 because without trays, you tend to get more spill over on the gums with resultant tenderness. May not be a problem for everyone and probably can be reduced by applying more carefully.

I just love 3d whitening pen it's clean out my almost stain specially you when you drink tea or coffee and it will removed all stains.its so convenient to carry it.
