Start with clean and dry aligners. Identify which are for upper / lower teeth. Note: It is recommended to wipe aligners with a tissue prior
to applying stickers.

Select the sticker to apply and peel off the clear rectangle that holds it.

Place the sticker rightside up on the upper aligner.

Rub the sticker on the aligner firmly to adhere.

Slowly peel away clear rectangle and discard, leaving the sticker on the aligner.
Note: if sticker adhesiveness is reduced during application, wipe aligner surface clean with a tissue before reattempting sticker application.
