Ultimate Guard Cortex 100 Standard Size Transparent Matte Sleeves are a solid choice for players and collectors looking for reliable protection for standard-size TCG cards. Developed by Ultimate Guard, one of the most recognized brands in the world of trading card game accessories, these sleeves were designed to offer durability, comfort in use, and a polished presentation for play decks and collections.

This pack includes 100 standard-size sleeves, compatible with cards measuring approximately 66 x 91 mm, the format used in many popular games such as Magic: The Gathering, Pokémon, Disney Lorcana, One Piece Card Game, and Flesh and Blood. This makes this product a versatile option both for those who play regularly and for those who want to keep cards protected during storage, transport, or display.

The Transparent Matte version stands out for its non-reflective matte front, a feature that is especially useful for reducing glare under strong light and improving card readability during matches, tournaments, or content recording. In addition, the textured back helps provide a smoother and more controlled shuffling feel, something appreciated by competitive players and by those who handle decks frequently.

Another important feature of these Ultimate Guard sleeves is their construction with acid-free and PVC-free materials, helping to better protect cards over time. The brand also indicates high durability and reinforced opacity, making this model suitable for intensive use in casual or competitive environments.
