Using your Thankful Variety Patch Tape for FreeStyle Libre 3 is easy. First, make sure the area around your FreeStyle Libre 3 device is clean and dry. Then, carefully apply the patch over the device, smoothing it out to avoid any bubbles. The patch should adhere well right away. When it's time to remove the patch, gently peel it off. It should come off cleanly without leaving any sticky mess. As for maintenance, the patch is designed to last up to 14 days, even through showers and workouts. But keep in mind that the actual printed patch may vary in color, design, and vibrancy due to production and material differences. Also, colors may fade over time with normal use. If you notice any signs of the patch coming loose or your skin reacting, it might be time to replace it.
