In a world where the difference between a graded Mint and Gem Mint can be a simple smudge or avoidable mark, why would you risk a bad grade with inferior products?
Guard The Grade
Sleeve Shield™ Helps Collectors Prep Cards with Confidence​
In a world where the difference between Mint and Gem Mint can be a simple smudge or avoidable mark, why would you risk a bad grade with inferior products?
Engineered differently than a standard microfiber cloth
Standard microfiber is fine for flat everyday surfaces like glasses, camera lenses, and screens. Sleeve Shield™ is built for a different job: helping trap and lift fingerprint oil and fine dust particles from your sports or trading cards.

How it works
Engineered to trap and lift fingerprint oil and fine dust particles
Drags dust, debris and oil across surfaces
Benefits
-
Ultra-Smooth "Low-Drag" Surface: Engineered with a high-thread-count polyester top to prevent micro-scratches during the cleaning process. Unlike standard textured playmats our Mat is a safe space
-
High-Contrast "Dust-Trap" Workspace: The top finish creates a professional black-hole effect for light, making every fingerprint, fiber, and speck of dust more visible. Identify surface contaminants before they ever get trapped inside a permanent slab.
-
3 mm "Safe-Pressure" Cushioning: Optimized density provides the perfect amount of "give" to apply cleaning pressure safely. This shock-absorbing core protects against pressure dents and corner dings that often occur when prepping cards on hard or thin surfaces.
-
Professional 16" x 24" Workstation: Larger than standard mats to provide a dedicated "Clean Room" environment. The extra depth allows ample space for your cards, cleaning cloths, and blowers, keeping your "to-be-prepped" and "ready-for-grading" stacks safely separated.
