Using these reindeer paper stickers 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 the sticker onto the pump, smoothing out any air bubbles as you go. When it comes to maintenance, just use a soft, damp cloth to gently wipe the sticker if it gets dirty. Avoid using harsh chemicals or abrasive materials as they might damage the sticker. Also, keep in mind that these stickers are for the pump only, and no devices are included with the purchase.
