I had a quick look, but although they have exotica like Maco, Forte and Bergger, they don't seem to list Efke. Their film seems a bit expensive, by the way.
Incidentally, I don't know if mail is xrayed. I received a second hand camera from the USA sent by DHL or UPS, I can't remember. The vendor had included some 120 film. I phoned the shiping company to ask if they xray packages. It seemed to be top secret. Maybe they don't want to tell terrorists what checks are performed. The person on the phone said that packages are "scanned." I asked "do you mean xray," and he said "scanned."
I haven't tried the film since it's something I don't use. (Scala, Fuji CN,..)
