Smileactives Teeth Whitening Pen for White Smile, Fast Tooth Whitener and Stain Remover with Precision Brush Tip, Dental Quality Whitening Gel, Travel Pen, Easy to Use, Ultra Mint Flavor, 2 Pack

Works well,

product does not work as quickly as described but my teeth appear to be getting "whiter".

Difficult to open and use, no instructions, pretty good product but packaging and lack of. Instruction is bothersome..

It works and its easy to use...what more could you ask for. Yes....it IS expensive...but wouldnt you rather spend your money on something that actually does what it us supposed to. Would love to see more flavor options!

After using for one month there is no difference in color of my teeth. I used on bottom teeth only so I could compare with top teeth to know if there was even a slight improvement. There is not. Bottom teeth should have been a shade lighter than top, but they are not.

No sensitivity! Best whitening on market

It works.

it's easy to use but way too expensive - it only does a so-so job of "whitening" your teeth :(
