I have some Medtronic Enlite sensors. Are they still usable if I donated them?

I don't use the Medtronic CGM, but I have a 3 boxes of leftover sensors from when I did. They're the MMT-7008A model number.

Would someone be able to use them even if they're a few years past the expiration date? The RX sticker says to use before 2018.

If anyone here wants them, I can ship them USPS.

I'd hate to throw them away if I don't need to.
