100ct Magnetic Card Holders for Trading Cards - Secure UV Protection

Our review of these 100 magnetic card holders finds them most useful for collectors who need simple, consistent protection for standard trading cards. The strongest reason to buy is the combination of a magnetic closure and UV-blocking acrylic that keeps cards visible while reducing risk of yellowing and surface scratches. In everyday use they feel like a practical, low-cost way to store cards you plan to display or archive, and the pack size makes them convenient for building or protecting a collection in stages.

Key Features

• Exact fit: Inner dimension of 2.52 in by 3.52 in ensures a snug fit for standard cards so they do not shift inside the holder.
• Durable thickness: The 35 point thickness provides rigid protection that helps prevent bending while handling or storing cards.
• Magnetic design: Built-in magnets allow quick opening and secure closing so cards stay seated and are easy to remove when needed.
• UV-blocking protection: The acrylic reduces UV exposure to help retain original card colors and slow yellowing over time.
• Diamond corners: Corner design keeps card edges from rubbing against the holder and minimizes abrasion over repeated use.
• Large pack quantity: A set of 100 holders gives collectors flexibility to protect favorites, rotate displays, or store sets together.

Who It's For

These holders are best for hobbyist collectors of sports cards and game cards who need safe, clear storage for standard 2.5 by 3.5 in cards, including baseball, basketball, football, hockey and MTG-sized cards. The pack size and clear acrylic make them well suited for building an organized collection without spending on single-purpose display frames.

Buyers who need archival-grade, sealed storage for extremely valuable or graded cards should look elsewhere, since these are convenient protective holders rather than tamper-evident or graded-case replacements. Also, if you require larger or nonstandard dimensions, these will not fit oversized or mini cards.
