Ultimate Guard Cortex Card Sleeves (100 Pack) - Purple Glossy, 66x91mm Standard Size
Ultimate Guard Cortex Card Sleeves (100 Pack) - Purple Glossy, 66x91mm Standard Size
These Ultimate Guard Cortex Outer Card Sleeves provide a glossy transparent front and a solid purple back for standard-size trading cards. Each pack contains 100 sleeves measuring 66 by 91 millimeters, made from polypropylene that is acid-free and PVC-free. They are designed to protect cards during play and storage while offering a smooth shuffle feel and high opacity to hide card backs.
Will these sleeves fit Magic: The Gathering or Pokémon cards?
Yes, they are standard-size sleeves, which fit Magic: The Gathering, Pokémon, and other TCGs that use the same card dimensions (66 x 91 mm). For smaller cards like Yu-Gi-Oh, you would need the Japanese-size version of these Cortex sleeves.
How clear is the glossy finish?
The glossy front side is transparent and high-clarity, letting card artwork show through with vibrant colors. It does reflect light in bright conditions, which is typical for glossy sleeves. If you prefer no reflections, a matte-finish version of the Cortex sleeves is also available.
Are these sleeves durable for regular play?
Ultimate Guard designed the Cortex line for daily use. The polypropylene material resists tearing and wear, and the sleeves are built to maintain their shape after many rounds of shuffling. They are an affordable alternative to the premium Katana sleeves while still providing reliable protection.

Common questions
Are these sleeves tournament legal?
Most tournaments allow sleeves as long as they are opaque and not marked. The opaque purple back hides card backs, but you should check with the specific event organizer for their sleeve rules.
How do they compare to Ultimate Guard Katana sleeves?
Katana sleeves are Ultimate Guard's premium line, with a smoother shuffle and slightly tighter fit. Cortex sleeves are more budget-friendly while still offering good durability and shuffle feel. Both are acid-free and PVC-free.
Do they come in other colors?
Yes, the Cortex line is available in multiple colors. This specific pack is purple. Other colors and finishes (glossy or matte) can be found separately.
