Review on 🦷 Supersmile Quikee Teeth Whitening Pen Stick - Guaranteed Treatment for Whitening Teeth and Freshening Breath On-The-Go - No Brushing Required - No Sensitivity - 30 Uses (Icy Mint) by Amanda Hall

I've tried a whole tube of this stuff and it works fast. The only thing that this little straw did well was that it gave me a feeling of freshness after I had dinner and didn't have a chance to brush my teeth. I didn't really notice a whitening effect. You can easily replace this with a small bottle of mouthwash on your desk and save a ton of money. It is also a great pain to apply. If you're looking for something that's easy to carry and can temporarily freshen your breath, then this might be for you. Otherwise, don't waste your time.
