They support you in achieving white, beautiful teeth and brightening your everyday life. 【A New At-Home Whitening Care That Lifts and Removes Stains】The high-concentration cleansing agent, sodium bicarbonate, adheres to and lifts stains and yellowing on teeth. Brushing afterward restores your teeth's natural shine. 【Easy 3-Step Care】Easy at-home whitening care with just three steps: apply, wait, and brush. Simply apply the sheet to your teeth, wait 20-30 minutes for it to settle, and then brush. This is a simple care routine, with 56 sheets (28 sets) that you can easily continue using. 【Precautions for Use】1. Some paste may remain on the tooth surface after using the sheet. Brush thoroughly with a toothbrush to remove any remaining paste. 2. If air gets trapped or saliva prevents the tape from adhering properly when applying the sheet, the whitening may appear uneven. The color will become more uniform with continued use, but it is recommended to wipe your teeth with a tissue before applying the sheet to remove moisture and prevent air from entering. 3. The sheets are for single use only. Please do not reuse them. 【Safe 12-Free Formulation】A 12-free formulation designed with your teeth in mind.
