Definitely work for me
Saw a review online and decided to try the bundle set with the promo. Am happy to say that it does help with coffee stains on my teeth! results can be seen in about 2 weeks for me.
i've tried a few other brands but using this bundle together with the Charcoal Powder provided the fastest results with continued usage for about 1 week. Can really see the effects of teeth whitening.
Saw significant whiter teeth in 1 week
Considering that I am an avid coffee drinker, I am very pleased with the whitening results from using this Bundle. I could see the significant difference in using this bundle in 1 week. Definitely will purchase again.
