FAQ
Rest assured. We use 5-ply reinforced, high-strength outer cartons (5-Ply Armor Packaging), complemented by high-density EPE foam and shock-absorbing bubble wrap inside, to ensure your order reaches you in perfect condition—with zero damage—after long-distance sea or air transport.
Not at all. The internal dimensions of the card brick have been precision-engineered through thousands of measurements (to exact 35PT specifications). When paired with the complimentary ultra-thin, custom-fit sleeve, the thickness is a perfect match; the card remains secure and stationary inside, with absolutely no bulging or bending.
The magnetic hold is incredibly strong. We’ve incorporated a high-torque, powerful neodymium magnet (2.5N) and paired it with a 0.6-inch "Easy-Opening Notch" at the top. This design ensures smooth, one-handed opening and closing with just a gentle flick, while guaranteeing that the case remains securely locked—without ever coming apart—even during severe drops or violent shaking.
Yes. KAAPAI features an ultra-slim 0.18" (approx. 4.5mm) design, making it nearly 50% thinner than the bulky standard cases (0.27" – 0.37") on the market. While maintaining military-grade drop resistance, it saves up to 30% of space in your card boxes, storage cases, or backpacks.
It is highly scratch-resistant. The surface features a 6H high-hardness scratch-resistant coating that effectively withstands friction from keys, coins, or handling during trade show setups, maintaining crystal-clear transparency over the long term.
To achieve 1:1 dual-layer protection. With standard magnetic card holders, the card comes into direct contact with the interior, making it susceptible to micro-abrasions on the surface and scratches along the edges caused by temperature fluctuations or movement. The 52 custom, high-clarity sleeves we provide fit perfectly inside the holder, creating a "sleeve-plus-holder" system that offers dual protection against dust, scratches, and friction.
This product is made from a high-density, shatterproof acrylic formula that offers exceptional impact absorption. It effectively absorbs the force of accidental drops during everyday use, ensuring the card inside remains completely undamaged.
The corners of a card are its most vulnerable points and the areas most prone to damage (such as "corner dings") that reduce its value. Our inner chamber features a precision-engineered, diamond-cut groove design that suspends the card's corners away from the hard plastic edges, completely eliminating the risk of "white edges" or creases caused by compression during insertion.
They will not fade. KAAPAI uses optical-grade, high-clarity acrylic with built-in, certified technology that blocks over 99% of UV rays. It effectively shields against sunlight, intense indoor lighting, and UV radiation, completely preventing your prized autographed or rookie cards from suffering paper yellowing, ink fading, or loss of value.
35PT is the standard thickness for collectible cards and is perfectly compatible with almost all standard 2.5" x 3.5" cards on the market, including: TCGs (Trading Card Games) such as Pokémon, Magic: The Gathering (MTG), Yu-Gi-Oh!, and Disney Lorcana; sports cards such as NBA basketball cards (Prizm/Select/Optic), NFL football cards, MLB baseball cards (Topps/Bowman), and soccer cards; as well as rookie and autograph cards.
Yes. Its precision magnetic sealing structure and interlocking edge design create a tight physical barrier that effectively blocks airborne moisture, sweat, dust, and accidental splashes, protecting paper cards from moisture damage.
It fits perfectly. With its thickness reduced to 0.18 inches, it is not only compatible with almost all standard card storage boxes (such as the KAAPAI 72-slot high-capacity box and EVA zippered binders) but also allows you to pack in 30% to 50% more cards compared to standard thick card cases.
Because KAAPAI focuses on "Industrial Luxury & Museum-Grade Defense." We offer premium features—such as ultra-strong 2.5N magnetic closures, over 99% UV protection, and shatter-resistant acrylic—and include 52 custom-fit sleeves as standard in every set. This delivers a comprehensive, top-tier protection solution right out of the box, offering a level of professionalism and value for money that far surpasses standard, generic card cases.
It takes just four simple steps: 1. Gently pry open the card case using the magnetic notch at the top; 2. Smoothly insert your prized card into the included custom-fit (1:1) protective sleeve; 3. Neatly place the sleeved card into the case's recessed area; 4. Align the back panel and snap it shut—secured by the strong magnet—to enjoy perfect protection.
