This is the original inventor of the Crypto Recovery Cassette product. They were kind enough to make it a shared license so other companies have made similar products. If you want the original, this is your cassette. Keep your recovery seed safe with stainless steel. Stop writing them down on loose scraps of paper. Cryptosteel is located in Manchester, United Kingdom. This design uses a mini screw driver to lock and unlock the device so that you can lower the latch on the side.
Cryptosteel is the original manufacturer of this style recover seed cassette. If you want the original from the UK, this might be your device. Cryptosteel is often out of stock and we are eager to get some of these in.
