Using these Santa stickers on your insulin pump is a breeze. First, make sure your 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, just use a soft, damp cloth to gently wipe the sticker if it gets dirty. Avoid using harsh chemicals as they might damage the sticker. Also, keep in mind that the purchase only includes the stickers, not the insulin pump device.
