Why Jeju families schedule reviews in autumn
Many reserve holders on the island prefer to complete their annual custody examination before the winter travel season, when family members who hold partial signing authority may be abroad. Panel Grove Field coordinates review windows that align with local bank vault hours and ferry schedules to mainland storage sites.
Our practitioners arrive with tamper-evident bags, photographic documentation kits, and pre-printed inventory ledgers. Nothing is connected to the internet during a field visit.

What reserve holders report after a review
The annual review surfaced two seed envelopes stored in different drawers that our family had assumed were duplicates. Panel Grove Field documented each phrase location separately and updated our custody map before we left the office.

Recovery rehearsal took longer than I expected because we had never tested the passphrase variant from 2021. The written drill report is now filed with our attorney. I wish we had booked the mid-year check-in as well.

Why Autumn Reviews Beat Winter for Jeju Reserve Holders
Jeju families who hold offline cryptocurrency reserves often discover in January that a key signatory is overseas and cannot attend a vault visit. Autumn reviews — particularly in September and October — align with local bank vault hours before the winter holiday rush and before ferry schedules tighten.
Vault access windows
Jeju City bank branches reduce safe deposit access hours during late December. Scheduling field visits in October means practitioners can photograph seal conditions and update inventory ledgers while all signatories are present.
Metal Seed Plates vs Paper Envelopes in Humid Jeju Homes
During home safe examinations in Hallim and Aewol, we regularly find paper seed envelopes with softened corners from humidity — even inside rated safes. Metal backup plates survive better but introduce labelling challenges when multiple signatories each hold partial records.
Paper envelopes
Affordable and familiar, paper backups fit attorney escrow workflows. They require desiccant packs replaced annually and explicit humidity notes in the custody map. We photograph envelope condition, not contents.
