Review on Venus Visage Teeth Whitening Pen: 2 Pens for 20+ Uses, Effective & Painless, Sensitivity-Free, Travel-Friendly and Easy to Use for a Beautiful White Smile with Natural Mint Flavor by Walter Harmon

The best teeth whitening product! I have used many products and this is by far the best! I even got a whitening kit from my dentist which was supposed to be very effective but it just burned my gums and the whitening wasn't as fast as with this product. I only bought it because it was cheap and had good reviews, but I didn't expect it to work because it was a lot cheaper than the doctor's kit, which cost me hundreds of dollars. It's very easy to use. It really works after the first use. Doesn't burn gums. It doesn't make your teeth sensitive.
