Using these stickers is a breeze. First, clean the surface of your Freestyle Libre 2 device where you want to apply the sticker. Make sure it's dry and free of dust. Then, carefully peel the sticker from its backing and align it on the device. Press it down gently starting from one end, smoothing out any air bubbles as you go. When it comes to maintenance, avoid exposing the sticker to excessive moisture or harsh chemicals. If it gets dirty, you can use a soft, damp cloth to gently wipe it. Remember, these stickers are for the device only, and no device is included with the purchase.
