This is a bulk refill for topping up self-custody kits. It is designed for users who create wallets regularly or manage multi-signature setups and need extra seed cards, envelopes, dice, wordlist, pens, stickers, and instructions.
The 10 × multi-signature envelopes are larger to securely store printed or laminated multi-signature wallet descriptors (e.g., XPUBs, policies, or configuration details) alongside seeds.
The 12-word and 24-word seed phrase cards are for recording BIP-39 seeds. They are useful for BIP-85 child seeds (e.g., gifting, spending wallets, travel hot wallets, or single backups), passphrase wallets, single-signature wallets, and multi-signature setups.
Yes—the pack includes materials for multi-signature (larger envelopes for descriptors) and supports any BIP-39 compatible multi-signature setup. You must understand multi-signature fundamentals for proper use.
SeedSigner is a base-level air-gapped device that every Bitcoiner should own. It serves as much as a training tool to deepen understanding of self-custody as it does a secure signing device.
Use the Edding 300 pen for SeedQR templates and the pigment-based pen for permanent seed recording. The waterproof BIP-39 wordlist is a durable reference during entropy generation or seed writing.
Official tutorials and documentation are available at seedsigner.com. NovaSapien’s online self-custody courses offer detailed support on wallet creation, backups, and multi-signature setups. You can also reach out to NovaSapien directly for assistance.
