The Ultimate Guard Cortex Matte Standard Size Black 100 Sleeves are a solid choice for players and collectors looking for reliable protection for standard-size TCG cards. Developed by Ultimate Guard, these sleeves were designed for popular games such as Magic: The Gathering, Pokémon, Disney Lorcana, One Piece Card Game, and Flesh and Blood, offering a very balanced combination of durability, comfort in use, and a refined presentation.

This pack includes 100 standard-size sleeves, measuring 66 x 91 mm, suitable for protecting traditional-format cards used in the main collectible card games. The matte finish on the front helps reduce glare when reading the cards and improves the playing experience in brightly lit environments.

The textured back contributes to smoother and more consistent shuffling, something especially valued by competitive players and by those who play frequently. Another important feature of these Ultimate Guard Cortex Matte sleeves is their high opacity, an essential characteristic for tournaments and for maintaining the visual uniformity of the deck.

In addition, they are produced without PVC and without acids, making them a safer option for those who want to preserve cards over time, whether in a personal collection, a daily play deck, or cards of greater sentimental and collectible value. The black color offers a classic, discreet, and versatile look, easily matching different styles of deck boxes, binders, and other gaming accessories.
