Using this insulin pump skin is a breeze. First, make sure your insulin pump is clean and dry. Then, carefully peel off the sticker from the backing. Align it with your pump and slowly press it on, starting from one end and smoothing out any air bubbles as you go. When it comes to maintenance, you can gently wipe it with a soft, damp cloth if it gets dirty. Just don't use any harsh chemicals. Also, remember that this is just a sticker, so the purchase doesn't include the insulin pump itself. If you need to remove the sticker, peel it off slowly, and it won't leave a mess on your device.
