smoke them and send him the ashes.
i use mailing tubes that you can buy at any office depot. get a size that will hold three or four cigars based on the diameter, and cut it to be an inch or so longer then the cigars. seal the bottom with some wide tape or a lot of narrow tape, shove in a paper towel, then the cigars, and then another paper towel.
that will keep the cigars from bouncing around and no can look into the end to see what you are mailing.
send it first class, regular old fashioned mail. it will get there almost as fast as priority which start at $3.85. don't insure it,. you never be able to collect from the post office.
