This is where the Cryptosteel Capsule comes in. Each kit comes with over 800 letter tiles which can be threaded onto the Capsule’s core to store each word of your seed phrase. Once complete, simply attach a fastener clip and screw on the steel cap.

It’s sturdy stainless steel build can withstand a house fire, flood and pretty much most things you can throw at it. Being pocket-sized also allows it to be hidden in many small and narrow places.
