Frequently Asked Questions

  • Preservation & UV Protection - Ultraviolet light — particularly in the 280–400 nm range — breaks down inks, fibers, and coatings through photodegradation, leading to fading, yellowing, and structural weakening over time.
    Even minimal exposure can accelerate aging. The Grail Case™ UVR Crystal Acrylic formula filters 99.9% of this radiation, ensuring your artifacts retain their original vibrancy and integrity.

  • Handling & Maintenance - Use a microfiber cloth and a pH-neutral acrylic cleaner (never alcohol or ammonia-based solutions).
    Apply light, circular motion. Never use paper towels or rough fabrics, which can introduce fine abrasions to the surface clarity.

  • Direct sunlight should always be avoided. Even with 99.9% UV filtration, the combined effects of heat and visible light can alter inks over long durations. For true archival safety, use LED lighting below 4000K and keep displays in climate-stable environments (30–50% humidity, under 75°F).

  • Yes — they offer limited UV resistance, but not full-spectrum protection. Over decades, even slight UV permeability compounds into visible damage.
    Grail Case™ serves as an additional archival barrier, creating a controlled optical environment designed for permanent display.

  • Design & Material Standards - A proprietary 10 mm museum-grade acrylic engineered for optical clarity and archival durability. It provides 92% light transmission for visual fidelity and filters 99.9% of UV wavelengths.
    Each sheet is UVR-tested and certified before production to ensure compliance with archival standards equivalent to those used by major museums and conservation institutions.

  • Thickness isn’t aesthetic — it’s functional. At 10 mm, the acrylic achieves structural rigidity, stable refractive index, and enhanced UV filtration consistency.
    Thinner materials risk micro-flexion and optical distortion over time, compromising both the seal and the visual presentation.

    This is why we call it The 10 Millimeter Guarantee — a standard, not a preference.

  • No. In fact, the opposite. The optical density of the 10 mm acrylic reduces edge diffusion and enhances color accuracy. The result is a floating, gallery-grade effect — true to life and distortion-free.

  • Each Grail Case™ Enclosure is designed for long-term preservation but can be safely opened and resealed using the included archival-grade fasteners.
    Avoid frequent handling, as repeated exposure increases environmental risk to the artifact.

  • Display or store in indirect lighting and controlled humidity (30–50%).
    Avoid proximity to heating vents or moisture sources.
    Like fine art, stability in temperature and light equals longevity.

  • Acquisition & Availability - Yes.
    Our manufacturing model guarantees a 24/7 in-stock inventory system, ensuring that preservation is never delayed by production cycles or “drops.”
    Collectors can select their enclosure at any time with full confidence in immediate fulfillment.

  • At present, Grail Case™ supports the three archival standards — PSA, CGC and TAG.
    Custom projects are selectively accepted for legacy collections and institutional archives by inquiry only.

  • Certification & Testing - Every production batch undergoes UVR spectrophotometric testing to confirm an average filtration of ≥≈99.9% per batch across the 280–400 nm range. After cutting and polishing the crystal acrylic, each case can vary slightly by fractions of percentages.  Some cases test at 100% UVR while some can test at 99.4% UVR 


    Testing conforms to standards equivalent to ISO 9050 and ASTM G173 for UV radiation exposure.

  • Yes. All materials used meet or exceed conservation-grade requirements consistent with museum display and archival storage specifications.
    The enclosure’s formula is acid-free, chemically inert, and designed for permanent preservation of cellulose-based and polymer-encased artifacts.
