Lab-Tested UV Protection You Can Trust

Independent testing using UV spectrophotometry confirms that Slab Saver acrylic provides exceptional ultraviolet protection, helping preserve the integrity and value of your graded comics and cards.

Key Findings from Lab Report


0% UV transmittance from 200–400 nm
This range covers harmful UVB and UVA radiation. These wavelengths are the primary cause of:
Color fading Paper degradation Yellowing and brittleness

~98.4% visible light transmittance (400–800 nm)
Allows nearly all visible light through. Ensures maximum clarity and display quality.
What this means: Your collectibles are protected from damaging UV rays without sacrificing visibility or presentation.

Why UV Protection Matters for Collectors

Ultraviolet light is one of the leading causes of long-term damage to comics and trading cards. Even indoors.

Without Protection
Ink pigments fade and lose vibrancy
Paper fibers break down over time
Slabs can appear aged or yellowed
Market value can drop 20–60%+
With Slab Saver
Blocks the most damaging UV wavelengths entirely
Preserves original color, contrast, and condition
Extends the lifespan of your collection

Museum-Quality Acrylic Clarity

Protection means nothing if it compromises how your collection looks. That's why Slab Saver uses high-grade, museum-quality acrylic engineered for optical clarity and display performance.
