The FreeStyle Libre 3 Plus system is a continuous glucose monitoring (CGM) system. The sensor is applied painlessly to the back of your upper arm and streams glucose readings automatically to your smartphone so that you can know your glucose anytime with a glance. You should know what they are if you are buying them.
These are two NEW SEALED boxes with an expiration date of 03-31-27. Each sensor is good for 15 days.
Selling on line for $90 EACH and up. As they are no longer needed I am asking just $50 each, both for $90.
