Using the Pump Peelz Spring Variety Tandem Mobi Patch Tape is a breeze. First, make sure the area on your body where you'll attach the patch is clean and dry. Then, carefully peel the patch from its backing and apply it smoothly onto the Tandem Mobi, pressing out any bubbles as you go. Attach the patched pump to your body using the Wing for Mobi or the Tandem issued sleeve. Remember, these patches alone won't attach the pump to your body. When it's time to remove the patch, gently peel it off. It should come off cleanly without leaving any sticky residue. To keep your patches in good condition, store them in a cool, dry place. Over time, the colors may fade a bit with normal wear and use, which is normal. If you have sensitive skin and notice any irritation, stop using the patch and consult a doctor.
