Using these insulin pump stickers is a breeze. First, make sure the surface of your insulin pump is clean and dry. Then, carefully peel the sticker from its backing and align it with your pump. Smooth out any air bubbles as you apply it. When it comes to maintenance, you can gently wipe the sticker with a soft, dry cloth if it gets dirty. Just be careful not to use any harsh chemicals or abrasive materials as they could damage the sticker. Remember, these stickers are for the pump only, and no devices are included in the purchase.
