The BluCon armband is designed to keep your Freestyle Libre sensor with the BluCon in place. No more worrying about your sensor being ripped out.
The elastic that goes around the arm is adjustable between 27-43cm, so it's suitable for children and adults.
Available in white, black, blue, gray and pink.
Note that this armband is only for the Freestyle Libre with the BluCon on top. If you don't have the BluCon then go with the Guardian Libre.
