The Ultimate Guard Cortex 100 Standard Size Yellow Sleeves are a solid choice for players and collectors looking for reliable protection for standard-size cards. Developed by Ultimate Guard, these sleeves were designed for TCGs and collectible card games such as Magic: The Gathering, Pokémon, Disney Lorcana, One Piece Card Game, Flesh and Blood, and many other formats compatible with standard cards.

This pack includes 100 yellow sleeves, ideal for building a complete deck with main cards and, in many cases, still having some room left for adjustments or replacements. The yellow colour helps to quickly identify the deck within your collection and is also an interesting option for organising by decks, formats, or themes.

Within the Cortex range, Ultimate Guard focuses on a balanced combination of durability, comfort of use, and careful presentation. These sleeves offer a highly transparent front to keep the artwork and legibility of the cards visible, while the textured back improves the feel when shuffling.

In addition, the high opacity makes them suitable for use in more demanding gaming environments, including tournaments, provided they meet the specific requirements of the event. Another important point for TCG fans, collectors, and regular players is the acid-free and PVC-free composition, a relevant feature for anyone who wants to protect cards over time and reduce the wear caused by frequent use.
