Teeth Whitening Pen Kit(5 Pens), Safe 35% Carbamide Peroxide Gel, Effective, Painless, No Sensitivity, Easy to Use, Travel-Friendly, 20+ Uses, Beautiful White Smile, Natural Mint Flavor

I love this stuff! This is by far my favorite whitening product.I am not a smoker but I am a coffee drinker. I've only been using this product for 5 days, but I already can tell a difference in the way my teeth look. They are not 100 percent white yet, although I do not expect them to be because it has only been 5 days.

Easy to use, and I really like the fact that the tubes are clear, so you really know how much solution is in each.

I use these instead of the expensive brand I used to get from my dentist. Works just as well. I will say they work better if you have custom trays, which I have from my dentist, that way the gel stays in place. I usually wear them with the gel on for about 15 min, 4-5 times a week

I've now been using this product for a few weeks. Although I have noticed that my teeth are whiter the results are nothing compared to what is claimed. I do have sensitive teeth so I appreciated the gentleness of the product. I didn't notice an increase in sensitivity so that was good at least.

I have been in Dental profession for near 30 years. I was hoping this would be effective in between cleanings. I gave it 3 consecutive tries, even right after my dental cleaning. Non effective. Will be returning. :(

This really works! The gel is effective and easy to use. I'm on day 7, and I can see a noticeable difference between now and before I started. Not only did it whiten my teeth, but it made my mouth feel fresh and clean. I'm very impressed with the results, definitely worth the price!

Just got it, but so far I love it! Can already see a small difference. Easy to apply and one of the best out there I think. Most teeth whitening kits are more complicated, and I love that it comes with 5 pens. I can gift 1 or 2 to a friend or family member

This Teeth whitening is impossible to not have your teeth get wet. It is not strong enough. My teeth did not get whiter.
