The Freestyle Libre Sensor Armband Holder is a flexible, durable, and biodegradable 3D printed accessory designed to securely protect your glucose sensor.

Lightweight and sweat-resistant, this armband combines eco-conscious materials with practical design to keep your sensor safe and comfortable all day long.

## Description

Product description This is a Freestyle Libre sensor arm band holder/guard. 3D Printed in flexible plastic. It is designed to protect your attached sensor and make it less likely that a knock will dislodge it. It is great to use it when your playing sports or swimming, where moisture or contact may make the sensor come loose. The armband can be adjusted with the two attached buckles. I recommend that you adjust the armband to the correct tightness on your arm below where the sensor is attached then lift the holder and place it over the sensor. To remove the armband I would press down on the sensor and gently lift the holder off and move the armband down your arm. The Freestyle Libre sensor is not included. The elastic arm strap may contain latex. 3D Printing works by laying down layers of plastic and therefore the surface finish will not be smooth like mass manufactured plastic parts and may have some visual artefacts. My pictures are always representative of the quality of finish you will receive. Please contact me if there are any issues I will always to my best to resolve them.
