Using this insulin pump skin is a breeze. First, clean the surface of your MiniMed 670G, 640G, or 630G insulin pump to make sure there's no dust or oil. Then, carefully peel off the backing of the skin and align it with your pump. Slowly press it down, starting from one end and working your way to the other, to avoid air bubbles. When it comes to maintenance, just use a soft, damp cloth to wipe it clean if it gets dirty. Keep in mind that this is just a skin, so no devices are included with the purchase. Also, try not to expose it to extreme heat or sharp objects, as this could damage the vinyl.
