This posting is for a total of 4 CGM. Dexcom Stelo. Brand new, unopened, unexpired. These are non-prescription and are regularly $50 each. Asking $30 each. They expire at the end of 2026 and last 15 days each. Each box contains 2 monitors, so you may buy one box for $60. I have been wearing these for a while and got a lot of good health info, I just don't need them any longer. Please text if interested.
