Foiled, bagged and in a book in a draw works for me with no loss of potency for quite a while.
Best way I've heard is that way, but with rubber bands on the book, and then the book in the freezer.
Nothing suss if your parents or anyone who you don't want to know about drugs opens your freezer lol
I do the foil, baggie, book method also and it seems to work well.
Putting the book in a few ziplock bags (for moisture) and then an opaque bag/container in the freezer might be the go so it doesn't look so dodgy
