I am not sure if they are operational yet.
"They are different from existing physical bitcoins as don't include keys on its back side. Instead they have unique IDs that can be binded to any Monero address within our site that is still in alpha and need more testing."
This was said 2 months ago.
Who operates this? Anyone has tried ordering?
I got one coin as a giveaway. They shipped it from China. I did not even paid for shiping.

This guy sent me. Ask him more about it, if on web page is no real contact.
I can only prove they were not just fair to me, but they also sent me free coin on their costs.
