Does the trick!
No gooey-ness or bad taste. Dispenses easily and works great with the blue light mouthpiece.

Not bad.

Snow is the best!
I think it is amazing. Ever since I have been using your product everyone compliments me on how white my teeth are. The whiteness of your teeth can take 10-20 years off your appearance.
I also use the whitening powder daily in conjunction with my toothpaste. SNOW is the BEST!!!

Definitely worth it!
I think it works pretty well, I ordered a kit 2 months ago and noticed a big difference. Ordered 2 extra strength pens. Pricey but totally worth it. I get a lot of compliments 😁
