## Editorial review

Stainless-steel capsule with letter tiles you arrange to store BIP39 seed phrases offline. Survives house fires, floods, and the heat-death of cheap paper backups. Made in Poland, accepts BTC. One-time payment, no recurring costs. Compatible with Monero 25-word seeds too (use word-prefix encoding).
