Using these snowman stickers is a breeze. First, clean the surface of your insulin pump with a soft, dry cloth to make sure it's free of dust and dirt. Then, carefully peel the sticker from its backing paper. Align it with your pump and slowly apply it, smoothing out any air bubbles as you go. When it comes to maintenance, avoid using sharp objects near the sticker to prevent scratches. If it gets dirty, you can gently wipe it with a damp cloth. Remember, the purchase only includes the stickers, so don't expect to get an insulin pump with it.
