I asked a clerk at a jewelry store. She said to clasp it, then put the necklace in a tiny zip lock bag with only the clasp part poking out. Close the zip seal. That's what they do.
What do you do with chains that are much thicker and longer than a drinking straw? PS I like your idea.

I found that putting each chain through a drinking straw keeps them from tangling with others and knotting! Lay them flat in jewelry box. Have done this for years with success.
