3 ZX Microdrive tapes

When I got my ZX Spectrum, it was buried under a pile of tuning capacitors and superheterodyne receivers, and I never noticed the 3 tiny little black boxes under a few 831 vaccum tubes. I don't have the actual microdrive, just 3 tapes in their casing.
I had a look at them, and the tape doesn't seem to be damaged. I won't ever use them, and nor do I want to.
