My brother aquired 2 boxes of Siglo II 5's for free, and because he doesn't smoke cigars, he'll be sending them to me

Thing is though, are the boxed cigars in cellofane? or are they just open?

I only buy one , two or three cigars a time, so I've never had so many cigars to deal with.
How can I keep them (if they aren't in cellofane) from fucking up over time? I don't have a humidor or anything.

£130 of cohibas going to waste isn't good
