Bitcoin Ingot: Plastic Bitcoin Wallet
Bitcoin cold storage that's more durable than a paper wallet. Use the public address on top to receive Bitcoin. Flip the wallet open to spend with the concealed private key.
The qr_models.py python script generates models from your own bitcoin address and private key. See "Instructions" for more complete instructions.
Note: That's not a real private key in the photo -- it's just a duplicate of the address. The address is real, however. Feel free to use it. :)
Be sure to test spending before relying on this thing.
