This is the box you’ll keep for the rest of your life. It will sit on a closet shelf, in a bedroom corner, eventually in your granddaughter’s closet. Every material inside it was chosen with that century-long timeline in mind — here’s exactly what we use, and why.
Most preservation services use ordinary cardboard with a gloss white coating, a sheet of tissue paper, and call it done. The cost difference between that and what we use is real — but so is the difference in what survives the next 100 years. Below is every component of our preservation chest, what it’s made of, and why it matters for the long term.
The Six Components That Make a 100-Year Chest
Acid-Free, Lignin-Free Construction
The chest is built from archival-grade board with no acid content, no lignin, and no gloss coating that off-gasses. Cheaper preservation chests yellow dresses from the inside out as the cardboard degrades. Ours doesn’t — the materials stay chemically inert for the full 100-year guarantee window.
UV-Protective Viewing Window
The 25″ × 13″ oval window is treated to block UV light so it doesn’t reach your dress. UV is one of the biggest causes of long-term yellowing in stored textiles. You can keep the chest on display in a room with natural light without compromising the fabric.
Acid-Free Preservation Bust
Inside the chest, your dress is fitted to a custom acid-free bust form. This is what prevents permanent creasing along the bodice and shoulders — without proper support, even perfectly cleaned dresses develop fabric memory and pleating that can’t be reversed. The same form museums use on ceremonial textiles.
Museum-Quality Acid-Free Tissue
Surrounding the dress inside the chest: archival-grade acid-free tissue, the same type used to wrap historic textiles in museum storage. It cushions delicate beading, prevents fabric-on-fabric friction, and won’t leach acids into the dress over decades of contact.
Three Custom Sizes
We build the chest in three depths — Standard, Large, and Extra-Large. Our boxing team selects the right size for your specific dress so it sits properly without compression. A slim mermaid silhouette and a full-volume ball gown both fit.
Heavy-Duty Outer Storage Box
The preservation chest ships inside a second high-density corrugated outer box with a handle. It protects the chest from spills, sunlight, small hands, and everyday household wear through the years — and generations — of storage, keeping the display chest in pristine condition.
Why — Honestly — This Costs More to Build
If you’ve compared preservation services and wondered why some are noticeably cheaper, here’s the actual reason. The cleaning chemistry is one part of the answer. The chest construction is the other. Side by side:
What Cheaper Chests Use
- Ordinary corrugated cardboard with gloss coating
- Acid-containing materials that off-gas over time
- Standard plastic film window (UV passes through)
- Polyfill or foam bust form (releases acids)
- Regular acidic tissue paper
- One-size box that compresses larger dresses
- No outer protective box
What We Use Instead
- Archival-grade lignin-free, acid-free board
- Chemically inert materials, no off-gassing
- UV-protective viewing window
- Custom acid-free archival bust form
- Museum-quality acid-free tissue
- Three sized depths for a proper fit
- Heavy-duty outer storage box with handle
Each of those upgrades adds real cost. Combined, they’re what lets us back our chest with a written 100-year anti-yellowing guarantee — certified to the original owner, and the longest in the wedding preservation industry. Many companies cap their warranties at 25 or 50 years, or skip them entirely.
The Other Half of the Story: How We Clean
The chest is one half of the 100-year preservation story. The other half is what happens before your dress ever reaches the chest — the museum-quality cleaning that removes the invisible stains that would otherwise oxidize and yellow over time. Without proper cleaning, even the best chest can’t prevent yellowing from perspiration residue, sugar deposits, and protein-based stains the dress carried in.
Our cleaning and our chest construction work together — neither one alone would earn a 100-year guarantee. Read about our museum-quality cleaning technology →
