Using this sticker is a breeze. First, make sure your insulin pump is clean and dry. Then, carefully peel the sticker from its backing and align it with your pump. Smooth it out slowly to get rid of any air bubbles. When it comes to maintenance, just use a soft, damp cloth to gently wipe the sticker if it gets dirty. Don't use any harsh chemicals as they might damage the vinyl. And remember, this purchase only includes the sticker, not the insulin pump itself.
