Using these stickers is a breeze. First, clean the surface of your insulin pump to make sure it's dry and free of dust. Then, carefully peel off the sticker from its backing and align it with your pump. Slowly press it onto the pump, starting from one end and smoothing out any air bubbles as you go. As for maintenance, keep your pump away from sharp objects to prevent scratching the sticker. Also, avoid exposing it to extreme heat or cold as this might affect the sticker's adhesion. Remember, when you buy these stickers, you're only getting the stickers and not the insulin pump device.
