Using these green fur 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 apply the sticker, smoothing out any air bubbles as you go. When it comes to maintenance, you can gently wipe the sticker with a soft, dry cloth if it gets dirty. Remember, these stickers are for the pump only, and no devices are included in the purchase. Also, don't try to force the sticker on if it doesn't seem to fit properly; just double - check the alignment and try again.
