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. Slowly place it on the pump, smoothing out any air bubbles as you go. When it comes to maintenance, just use a soft, damp cloth to wipe it clean if it gets dirty. Remember, this purchase only includes the sticker, so don't expect a device to come with it. Also, handle the sticker gently to avoid any tears or damages during application.
