Hi Jeremy,I have these jewelry bags called prezerve,they are meant to preserve sterling silver, so it won’t tarnish for up to 25 years. I keep my pearls in these bags because I don’t have a lot of space for storage.Is this a safe way to preserve my pearls or should I find another way,? Do you make anything like it but for pearls? I’m concerned that air does not flow.Can you please advise?
