Using this insulin pump skin 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 and align it with the pump. Slowly press it down, starting from one end and smoothing out any air bubbles as you go. When it comes to maintenance, you can gently wipe the sticker with a damp cloth if it gets dirty. Just avoid using harsh chemicals or abrasive materials as they might damage the sticker. Please note that this purchase only includes the sticker, so you won't receive an insulin pump with it.
