I've acquired quite a bit large number of shaving brushes and getting them all in the rotation seems unlikely. I want to save some for the future just in case, and these brushes include badgers and synthetics. I just wanna know if it's okay to keep them in their original boxes, unopened and unused. I suspect badger is protein substance and might need to "breathe". Is it okay to keep them as is, piled in some secret place where wife can't find them? Any feedback is appreciated.
