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 press it down, starting from one end and smoothing out any air bubbles as you go. When it comes to maintenance, keep it away from sharp objects to avoid scratches. If it gets dirty, you can gently wipe it with a soft, damp cloth. Just note that this purchase only includes the sticker, not the insulin pump device.
