Hey,
I have started to make limited edition bitcoin bottle caps inspired by the nuka cola caps from the fallout game. Each cap is limited to 100 of each design and comes with a QR code linked to the Bitcoin block chain securing the verification document for your cap.
Each cap will come in a decorative glass gas with the QR code visible to scan without removing it from the box each cap will be marked on the back what number it is then the QR code will verify the number once scanned.
We have only just finished our first one as our demo please see pictures below:
I apologies in advance for the bad photos if their not that good i have a really bad phone.
Message me if you're interested in getting one :)
