The 99.9% UVR Standard
Ultraviolet radiation is invisible, silent, and irreversibly destructive — breaking down the chemical bonds in inks and paper fibers through photodegradation, causing fading, yellowing, and brittleness.
The Silent Adversary
Research from the Library of Congress shows that a single year of moderate light exposure can age paper as much as ten years kept in darkness.
For collectible assets, that means slow, certain decay — often before the human eye can detect it.
Even the most trusted slabs — PSA, Beckett, CGC, TAG — reduce but do not eliminate this exposure.
Preservation begins where light ends.
The Material Difference
Grail Case™ uses a proprietary UVR Crystal Acrylic Formula engineered for both museum-grade transparency and archival-grade filtration.
The 10 mm thickness ensures optical consistency, structural rigidity, and the density required to absorb ultraviolet wavelengths up to 400 nm — the range most responsible for card degradation.
Where others use generic acrylic with unverified claims of “UV protection,” Grail Case defines and documents the result: 99.9% resistance to UV light.
Transparency without compromise. Preservation without question.

The Verification Process
Lightfastness & Transmissivity
Every Grail Case batch undergoes independent UVR testing against industry-recognized standards for lightfastness and transmissivity. Engineered for preservation. Proven by science.
UV Spectrums
Measured Before Production
Each sheet of crystal acrylic is measured prior to production across UV-A and UV-B spectrums to confirm less than 0.1% transmittance on average.
Lightfastness
Proven Resistance
Lightfastness is a material's ability to resist fading, discoloration, or other change when exposed to light — especially ultraviolet rays from the sun.
The Grail Case Process
One Consistent Standard
This process ensures every enclosure that bears the Grail Case™ mark delivers the same level of archival protection.
The Purpose Behind The Standard
The 99.9% UVR Standard is more than a specification — it is a promise of permanence.
For the collector, it means the reds remain rich, the whites remain pure, and the gloss never dulls. For the Grail itself, it means the artifact can exist in light, without fear.
Because what you preserve is not just ink and paper — it's legacy.
The Guardian of Grails, defined by science.
“I'm detail-oriented. When I saw the 99.9% UV rating and the batch testing standards, it felt different from the usual marketing claims. That level of filtration makes a real difference over time.”
“Knowing that 99.9% of harmful UV radiation is filtered out changes how I display my collection. I still avoid direct sunlight, but I'm not constantly anxious about ambient light anymore.”
“It disappears — in the best way possible. Crystal clear, perfectly cut, no distortion. Just protection.”

99.9% UV Resistant
The reds remain rich, the whites remain pure, and the gloss never dulls. Give your grails the case engineered to protect what time can never replace.
