Step 1: Tear it apart - Wipe the tooth surface before use and gently peel off the dental strips. Step 2: One post - Gently pull the strips left and right, stick them on the tooth surface along the gum line, and fold the excess part toward the back of the teeth to stick the long strips on the teeth and the short strips on the lower teeth. Step 3: Safe whitening - Take it off after 30 minutes and leave it on for another 30 minutes for a 30% whitening bonus.
