Wecome! lThere is no requirement to keep your
MC in original tubs or pouches at home. I keep them with the related script and use them if I am out only. Put your smaller dark jar ( many sizes available) as JA linked above in the tub if out.
The tubs give a nasty plasticky smell to the flos in the experience of many, sometimes a slightly " singed" smell due to the heat sealing.
I then use suitably sized clip lock food boxes to store jars of unground flos in jars, you will find that keeps the last smells locked away ( contamination of the jar, lid will create a smell as well as imperfect seal) and as fresh as you like.
Many people use 62% hydration packs to keep humidity of
MC flos at a stable level.
