Using this sticker 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 debris. Then, carefully peel the sticker from its backing, align it with your pump, and slowly press it down, smoothing out any air bubbles as you go. When it comes to maintenance, just wipe it gently with a damp cloth if it gets dirty. Don't use any harsh chemicals as they might damage the sticker. Also, note that this purchase is just for the sticker, and no insulin pump devices are included.
