Using these Omnipod DASH™ marshmallow charms is a breeze. First, make sure your device is clean and dry. Then, carefully peel off the backing of the vinyl charm and align it with the area you want to decorate on your OmniPod Dash PDM. Smooth it out gently to get rid of any air bubbles. When it comes to maintenance, just use a soft, damp cloth to wipe it clean if it gets dirty. Remember, the purchase only includes the vinyl Peelz, not the case or any devices. So don't expect the whole setup in your package.
