This stuff really works!! I used these strips for about three days and already noticed a HUGE difference! You can especially tell in pictures as it literally looks like someone bleached your teeth (in the best way)! The strips stick to your teeth, so it’s easy to keep them on for 20 minutes. Love these!

The best white strips I have ever used, whitens teeth after only one use. These ones also don’t make my teeth super sensitive like most white strips do. The only reason I give these 4 stars is because the price.
