Review on Whitening Effective Sensitivity Travel Friendly Beautiful by Andrea Olson

My teeth are fairly white but I'm an avid tea and coffee drinker so my bottom teeth tend to get stained from time to time and a few teeth are in the same spot/pattern so that's it it perfect to test these pens for teeth whitening brand Vaclaw. At the time of review, a small box of 4 pens (over 35 uses per company, not tested by me) cost $9.99, which is roughly $2.49 per pen. I've been using these pens for 11 days, mostly once a day when time permits. So not quite as stated. I also didn't wipe my teeth (with a napkin) or "smile" for 30 seconds to 1 minute as directed by the instructions (but I didn't eat or drink until 30 minutes were up and some applications were applied at night) . . ) so keep that in mind. As with most rotation/gel pen objects, starting a new pen requires several rotations before the gel becomes visible. Once this has happened, a few turns are usually sufficient for the application. I usually have some sensitivity to lightening products - so far I haven't had them at all with the method I've used and I don't think they would be harsh enough if I used them exactly as intended. My teeth are at least 2 shades lighter and the stain I followed is very matte (typical of this stain and other whitening products). They are cheaper than your regular whitening strips or trays and you can use them as you please, easy to take with you and/or save the pens for other occasions. They certainly work and are good value for money.
