The Self Custody Supplies – Storage Containers provide two practical options for securely storing and organizing seed phrases, passphrase cards, multi-signature descriptors, and other wallet materials.
Lockable Zippered Sleeves ($35 for 3)
These discreet, low-profile soft cases feature lockable zippers for added security, a padded Tricot fleece interior to cushion contents, a removable reflective ID patch for instant identification, and a durable 600D PVC shell for everyday protection. Each sleeve measures 12.25″ × 8.75″ × 0.5″ (full size) with an internal size of 11.5″ × 7.5″. They are a simple, functional solution for users wanting additional secure storage for seed phrase cards, passphrase materials, or printed multi-signature descriptors.
Fire-Resistant Zippered Cases ($25 for 3)
These cases are made from fire-resistant material to protect contents from extreme heat (e.g., in a fire where they are stored inside a safe). While seams may melt in direct flame exposure, the material provides reliable heat resistance for most real-world scenarios. They offer padded protection and secure zippered closure for seed cards, envelopes, or backup materials.
Both options support best-practice multi-backup strategies: we recommend creating 3 backups of each seed phrase and 3 backups of each passphrase, stored in geographically separate locations.
These containers can be purchased together with the NovaSapien Self-Custody Kit – Sovereign Backup System for a complete self-custody solution that pairs secure storage with comprehensive backup materials.
NovaSapien’s online self-custody courses offer detailed, step-by-step guidance on seed management, backups, and multi-signature setups. You can also reach out to NovaSapien directly for assistance. Official resources are available at seedsigner.com.
