10% 4pk (4 gels)

I did see an improvement on the whitening of my teeth. This is the same brand that I always bought from my dentist office. Would recommend to others.

This product is GREAT! After 2 weeks my teeth were white, and I never had any sensitivity on my guns. I recommend to anybody who cares about having nice and white teeth. I think that you may use all the make-up in the world, if you don't have nice teeth you wiil look old and unhealthy, no matter what.

No white teeth

Excellent. I will be purchasing this item again.

Excellent product and value.
