Review on 🦷 HOPEMATE Teeth Whitening Pen (2 Pens) - Professional Dental Whitener for a Bright, Flawless Smile by Emily Armstrong

I only ordered this because I got a good discount on an online coupon that increased the price from $39 to $12. I'm a profitable buyer. These are 2 pens, I gave one to my friend and I used the other. We both haven't been to the dentist in a long time, so my teeth weren't that white anymore. The box is tiny and you have to turn it many times b4 that's all it takes to start and the good thing is that it doesn't taste bad and doesn't sting in the mouth like the others and it seems like it has whitened our teeth a bit but that was it 1 application. Will I pay $40 to buy again? I don't think so, unless when my hands are empty my teeth almost glow. For the $12 I paid it wasn't bad. Let's see how long that lasts and how much whiter than to decide.
