Acid-Free Materials for Folders That Last Decades

Heir folders are meant to sit in a safe or filing cabinet for ten, twenty, or thirty years. Standard copier paper yellows within years in Korean summer humidity. We use acid-free 80gsm paper rated for archival retention.

Binding uses cloth-covered boards with reinforced spine stitching — not spiral coils that crush, not glue-only bindings that fail when pulled from tight shelves. Cover labels are embossed rather than adhesive, because adhesive labels peel and leave unreadable residue over time.

Numbered tabs are polyester film, not paper tabs that tear when heirs flip through sections during a stressful phone call at midnight. Each tab color corresponds to a storage location category: home, institutional vault, third-party custodian.

Photographs are printed on matte archival photo paper and dry-mounted — not inserted as inkjet prints that bleed when folder pages absorb moisture. For clients in coastal Gyeonggi properties, we recommend silica gel packets in the folder slipcase, which we supply at delivery.

The slipcase itself is rigid board with a closure band. It protects the bound folder from dust and light exposure while allowing heirs to remove the volume without damaging the spine.

Material cost is part of why our folder preparation starts at ₩480,000. Cheaper bindings fail. A folder that falls apart when heirs need it has no value regardless of how carefully the contents were written.
