Simply apply the sheet to your teeth, wait for 20-30 minutes, and then brush. This is a simple care routine. 28 sheets, 14 sets, allow for easy continuation. 【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 tape, the whitening may appear uneven. The color will even out 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.
