Using these stickers is a breeze. First, make sure your Tandem device is clean and dry. Then, carefully peel the sticker from its backing and align it on your device where you want it. Smooth it out with your fingers to get rid of any air bubbles. When applying, take your time to ensure a perfect fit. As for maintenance, avoid rubbing the sticker too hard. If it gets dirty, you can gently wipe it with a soft, damp cloth. Also, keep in mind that the purchase doesn't include the Tandem device. Enjoy decorating your device with these cool stickers!
