Using these tie - dye stickers on your insulin pump is a breeze. First, make sure the surface of your insulin pump is clean and dry. Then, carefully peel the sticker from its backing and align it with your pump. Slowly press the sticker onto the pump, smoothing out any air bubbles as you go. When it comes to maintenance, simply wipe the sticker with a soft, damp cloth if it gets dirty. Avoid using harsh chemicals. Also, keep in mind that these are just stickers, so no devices are included with your purchase.
