They came in just a standard off white-ish envelope, about 6" by 8" in size. I definitely wouldn't say it was stealth packaging heh. They were taped to a piece of cardboard to keep them lined up in their own seperate packaging (and to make it opaque if you held it up to the light). All in all I'd say they arrived in excellent condition. I threw out the envelope but I don't think there was a return address, although I knew it was foreign as there was a Royal Mail stamped on it.

Now, just waiting on the other half of the order to get here.
