The hygometer kit, the humidor packs, the seasoning packs are all the exact same product. Just labeled differently and at different RHs.

The hygrometer kit actually works pretty well if you leave it unopen for the time is says to on the package. I once used it to calibrate 5-7 Western Digitals over a period of a week and they were all surprisingly close to each other. But you have to leave it for the full 24-36 hours, after 7-8 hours it is still all over the place.

I am not sure I would trust the larger packets though as the kit uses a really small volume. Also, if you have the smaller 69% packets they use for shipping, I would not trust those as they dry out really quickly.
