A paper wallet is the Secret Key by itself, most often written or printed on paper and sometimes with QR codes for easy transfer.
Although the Public Key and Address can be derived from the secret key alone, a paper wallet will often have the address printed with it so that more funds can be sent to that address.
A paper wallet should only be used if it was securely generated. Paper wallets must be kept safe, as elsewhere discussed a piece of paper can be destroyed in many ways.
Creating an encrypted wallet of your own is a safe way to store your Cryptos without having to trust anyone. When you generate your own encrypted secret keys securely you can share the secret key without worry.
Use long, random pass phrases and generate from a secure and always offline machine. Use websites like https://ryepdx.github.io/ethaddress.org/#/ for ETH or http://bitaddress.org for BTC
Generating securely isn’t that easy though. A computer needs to be used that is either dedicated offline and airgapped, or a RAM-only Operating System needs to be used offline. This is to ensure that no ‘computer viruses’ can watch you and steal your keys. The ladder option can be obtained by using a plug-and-play operating system such as Tails.
In addition to using a secure system the pass phrase needs to be long and random. At least 10 words is recommended minimum, more is better. Never use anything from any published work no matter how obscure. Always use random words, use Diceware or dice and wordlist to obtain random words. This pass phrase, and the website or method used to encrypt the wallet are crucial to spending it, you cannot lose them. You can save a website for using in the future or even for online use. To do this rightclick and hit save. Practice before the game.
The first edition capsules have no numbers nor markings on the end pieces. The second edition capsules have a number laser engraved in the inside of the inner ring which you can read with a flashlight.
Enough material was created for 50 of each the 1st and 2nd edition capsules; but less were available to be made due to errors, accidents, and testing.
Of the sapphire blue and ruby red centerpieces only 25 of each were custom made for the Keyois Capsule.
The simulated alexandrite was also custom for the second edition.
Although the Keyois Capsule was designed with these vials in mind it turns out there are rules in the US against repackaging tritium into toys without an expensive license.

Cold storage is a term for an address or wallet which was: securely generated, has never been exposed to the internet, has never been spent from, and is often used as a long-term storage. It has been equated to a savings account at a bank.
Compare this to a ‘hot wallet’ which has either been used in the past and spent from or is being used regularly (such as a hardware wallet).
A secret key or seed (usually encrypted) is engraved within the tamper evident capsule. The capsule contains a visibly engraved address that can be funded from the outside. Like a piggy bank you have to break the bit-capsule open to get access to the funds.
After you order and receive your package you may wonder how to open it. After taking out the unique sealed container just tap it with a hammer once or twice to reveal the goods inside.
They serve no functional benefit aside from being pretty, but did you know the first laser was made with synthetic ruby?
Key-Oh-sss
It’s a cryptocurrency piggy bank, you’ve got to destroy it to spend it. There are lots of ways to break it apart.
For example crushing it with a back-hoe works to expose the rings by opening the capsule.
A hammer and some props should suffice to get the titanium rings apart after freeing them.
Always wear gloves, eye, and ear protection when cutting glass and metal and be safe!
Yes however tools and work are required to assemble the item.
Simply add a capsule like normal to your cart and in the checkout screen under the ‘special instructions area’ make a note to please ship the capsule unassembled.
All the capsule hardware is included, including centerpiece of choice and custom engraved ring-pair.
The following are recommend items for assembly: high-strength epoxy to seal the rings and optionally reinforce the endpieces to the supports; high-strength threadlocker for the screws; a screwdriver and torque driver / screw gun to tighten the screws; a drill with a metal cutting drill bit between sizes 11/64 and 13/64″ to drill out the screw heads.
Yes! If there is a public address and a secret set of information.
As length goes up legibility goes down. To fit the secret key or seed on the smaller metal ring the font size must be smaller than the address ring. About 65 characters can fit one one line of the secret key.
The first edition capsules have no numbers nor markings on the end pieces. The second edition capsules have a number laser engraved in the inside of the inner ring which you can read with a flashlight.

Google is your friend!
BIP38 can seem daunting but there are many very helpful guides across the internet.
Create a secure pass phrase in a random way, then use a site like bitaddress or bip32 on a secure computer to generate a wallet. Once this is done you shouldn’t fear showing anyone your encrypted secret key if your pass phrase is secure.
If your only copy of the encrypted secret key is inside a keyois capsule you can keep your capsule safe while making copies or splitting your decryption key.
These are just a few of the many guides available online:
