Using this insulin pump skin is a breeze. First, clean the surface of your insulin pump to make sure it's free of dust and oil. Then, carefully peel off the backing of the sticker and align it with your pump. Slowly apply it, smoothing out any air bubbles as you go. When it comes to maintenance, you can gently wipe it with a soft, dry cloth if it gets dirty. Keep in mind that this purchase only includes the sticker, so don't expect to get an insulin pump with it. Also, make sure the vinyl doesn't get in contact with sharp objects to avoid scratches.
