Using these Christmas Berries stickers is a breeze. First, clean the surface of your MiniMed insulin pump to make sure it's dry and free of dust. Then, carefully peel the sticker from its backing and align it with your pump. Slowly press it down starting from one end, smoothing out any air bubbles as you go. When it comes to maintenance, avoid using abrasive cleaners on the sticker. Just use a soft, damp cloth to wipe it clean. Remember, these stickers are for the pump only, and no devices are included with the purchase. If you notice the sticker starting to peel at the edges, you can gently press it back down. And that's all you need to know to enjoy your stylish insulin pump stickers!
