Using our disco balls sticker is a breeze. First, clean the surface of your insulin pump to make sure it's free of dust and grease. Then, carefully peel the sticker from its backing. Align it with your pump and 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 wipe the sticker gently if it gets dirty. Don't use harsh chemicals or abrasive materials as they might damage the sticker. Also, remember that the purchase only includes the sticker, no insulin pump device is provided.
