This is a holder for your Miaomiao reader to secure it to the libre sensor.
You can put the double sided tape that comes with the Miaomiao on the back off the holder to secure it on your arm, you dont need the use the eye sticker to secure it to the sensor, it keeps the sensor firmly in its frame, just put the holder over the sensor and snap it to place.
This way when you need to remove the Miaomiao you are not at risk to loosen the sensor.
-No stickers are included
