Applying these stickers is a breeze. First, clean the surface of your Freestyle Libre 2 device to ensure a good stick. Then, carefully peel the sticker from its backing and place it on the device. Smooth out any air bubbles with your fingers. When using the device with the sticker on, be gentle as you operate the buttons and sensors to avoid peeling the sticker. To keep the sticker looking great, avoid exposing it to excessive heat or moisture. If it gets dirty, you can gently wipe it with a soft, dry cloth. Also, don't forget that these are just stickers and no device is included in the purchase.
