BLAQ Activated Charcoal Teeth Whitening Pen - Travel Size Tooth Whitener Wand Removes Wine, Smoke, Coffee Stains - Natural Tooth Whitening Pen - Breath Freshener & Smile Brightener 2g/0.07oz

I noticed a difference after the first use, it definitely Works. It’s a bit of a challenge to hold you lips open so it dries (a whole minute?!), but it tastes good and doesn’t cause any sensitivity.

The consistency of this is really… gloopy. I cannot tell a difference in the color of my teeth. I’ve tried other teeth whitener pens and I would pick the dollar store one over this. Really bad.

Love this product and this Brand!!! I could tell a difference after just a few uses. Read the directions and follow them in order to get results advertised.

The brush at the end of the pen remained completely dry, no matter how many times I turned the dial on the other end. It was a complete waste of $20.

I liked that it left my teeth feeling clean but not sure how white it made them. I will continue to use in hopes my teeth keep getting whiter

Loved everything about this product. I can see the lighter shade on my teeth.

It does not really do a significant difference

Teeth felt cleaner after use but I did not notice much whiteness after 2 weeks of use.
