Using this sticker is a breeze. First, clean the surface of your insulin pump to make sure it's dry and dust - free. 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, you can gently wipe it with a soft, damp cloth. As for precautions, avoid using harsh chemicals on the sticker. Also, remember that the purchase only includes the sticker, not the insulin pump.
