Long term butter stores DIY.

[Nemesis]

I never use the wax lids on butter is about the best I can offer, this is not my field but it is something I do, I would have to leave that up to you NR if you should or should not use them, but I would say do both with and without, and in a years time open both and let us know.

I do use plumbers tape and will show you how and why when I update this thread.
