Storage advice needed

[S.Workman]

Hello everyone, I have a few keris that I like a lot. My kids, however, have some doofus friends that I would rather not be messing with any blades, much less my keris. I think my collection needs to go into storage, before something dumb happens. Does anyone have advice on the medium term storage of keris? Most particularly I am interested in what type of dun age I can pack them with.
