Crest 3D White Whitestrips Professional Effects is thin, flexible strips that are coated with a tooth whitening gel. It is formulated with the same enamel-safe ingredient that dentists use.

Designed to conform to the shape of your teeth, they work by keeping the whitening gel on your teeth for 30 minutes once a day to get at stain build-up on and below the tooth's surface. You'll start seeing a whiter smile after 3 days.

The Advanced Seal Technology provides a form fit, no-slip grip that molds and adheres to your teeth for a bitter whitening experience. In fact, you can even drink water while wearing Whitestrips with Advanced Seal technology.

The product is Made in USA with High Quality. It is 100% Brand New and Authentic.
