That depends on several factors. The seal and type of box. The conditions that the box is sitting in. At what level of humidity the cigars came from (some vendors ship at a high humidity). On and on. I would set yourself up a simple tupperware container if you don't have anything else to put the cigars in. Grab a tuppware that the cigars will fit into, and use a bit of distilled water in a small container or floral foam. It will be better than nothing. Be sure to open the tupperware every once and a while to let it breathe. Also, I would only look at this for a short term storage option.
