Ultimate Guard Cortex Outer Card Sleeves – 100 Standard Size, 66x91mm, Green Back, Glossy Finish, Acid-Free

The Ultimate Guard Cortex Outer Card Sleeves are designed to hold standard-size trading card game (TCG) cards, measuring 66 x 91mm. Each pack contains 100 sleeves with a glossy finish on the front and a green back. They are marketed as PVC-free and acid-free, aiming to protect your cards without damaging them over time. These sleeves suit players who want clear visibility of card artwork combined with a colored back for deck organization.

Key Specifications at a Glance

Glossy Clarity for Card Artwork

The glossy front of the Cortex sleeves is engineered for high transparency. This lets the colors and details of your cards stand out without distortion. Whether you're playing with a foil card or a rare collectible, the sleeve aims to preserve the visual impact of the original print.

Built for Repeated Shuffling

These sleeves are designed to slide smoothly against one another, which helps with consistent shuffling during games. The edges are cut to minimize catching or splitting, common problems with lower-quality sleeves. While no sleeve is indestructible, the Cortex sleeves aim to hold up through many game sessions.

Opaque Backs for Privacy

The green back features high opacity, meaning it blocks any information from the reverse side of the card. This is especially useful in games where players should not see card backs through the sleeve. It also helps in sorting decks by color or set without confusion.

How do Cortex sleeves protect your cards?

The sleeves act as a barrier against dirt, fingerprints, and light wear from handling. Because they are acid-free and contain no PVC (per the description), they are less likely to cause chemical damage to card surfaces over long-term storage. For daily play, the glossy front resists scratches better than a matte finish might, though glossy surfaces can show fingerprints more easily.

Frequently Asked Questions

Are these sleeves compatible with other sleeves? Can I double-sleeve?

The Cortex sleeves are classified as outer sleeves. They are sized to fit standard TCG cards (66x91mm). You can use them as outer sleeves over an inner sleeve, but check the total thickness; these are designed primarily as standalone sleeves. The manufacturer does not specify double-sleeving in the provided data.

What game cards fit the 66x91mm size?

This size is standard for many trading card games such as Magic: The Gathering, Pokémon TCG, and others. The sleeves should fit any card that meets the standard 63x88mm card size, with extra space for the sleeve border.

Is the green back the only color option?

The product data specifies a green back for this item. Ultimate Guard offers Cortex sleeves in other colors, but this particular pack is green.

How many sleeves are in a pack?

Each pack contains 100 sleeves, enough to protect a typical 60-card deck with spares, or a 100-card Commander deck.
