How creative you are...
These are 4" x 6" and yes, you can mail them as long as they are not more than 1/8" thick and have the word "postcard" at the top on the back.
I have mailed such things many times and as long as you follow the rules, you can mail a bottle or a rubber plunger or other such things.
No you can't mail it with designs on both sides. Those are going to some local people that want them just to put on their desks.
