the site states that the "address" is also under the hologram and makes it seem as though they should be loaded.
The "private key" & "address" is on a paper embedded inside the coin and is protected by a tamper-evident hologram.The hologram leaves behind a honeycomb pattern if it is peeled. If the hologram is intact, the bitcoin is good.
edit - I read further and it states that these were DIY and assembled but yes, not preloaded by manufacturer - if they assembled they included a separate list with address(es)
Way 1 : Order the coins , print and put the Key&address by you self then transfer your bitcoins into the address in the coins.
you can easy and safe print ramdon key&address by using the generator web. Here
Way 2: Order the coins with ramdon key&address already. transfer your bitcoins into these address.
we will send you the coins with a address list, and Extra tamper-evident hologram, so you could verify the coins.
