Using these vinyl Peelz is a breeze. First, make sure your OmniPod Dash PDM case is clean and dry. Then, carefully peel off the backing of the vinyl Peelz and align it with the case. Smooth it out gently to get rid of any air bubbles. When it comes to maintenance, you can wipe it with a soft, damp cloth. Just don't use any harsh chemicals. Remember, the Peelz are for the case only, and no devices are included in the purchase.
