I'm beginning to think when buying an OCS stamp that:
or:
- the right part is removed, thereby maybe only the left part (post stamp 6,90) is shipped
Since:
TRANSFER YOUR CRYPTO STAMP:
As the owner of this crypto stamp, you can transfer this asset to any wallet...
SHIPPING OF THE PHYSICAL STAMP
This asset is for sale or purchased from the OnChain Shop.
...
The digital asset has been submitted to the buyer wallet.
The owner arranged for the physical stamp to be sent...
or:
- the right part looks differently
or:
- it just comes in the 2 parts,
since the seed phrase [2] belongs to the first wallet (OnChain-Shop) address [3] IF the asset is linked to that address.
When the asset is linked to another wallet during purchase, you cannot do anything anymore with the address [3]
and seed phrase [2] hidden under the scratch fields, so the codes [2] & [3] on the second part don't matter anymore.
The first address contains 0 Crypto stamp and the asset can then only be moved by its new owner through his (ETH) wallet...
Sorry for thinking too much out loud here

Can't wait to discover its true nature!
