Cortex Sleeves are specifically designed to be the optimal cost-effective sleeves for daily usage

While our Ultimate Guard Katana sleeves represent the pinnacle of our craftsmanship, the Ultimate Guard Cortex sleeves offer a compelling alternative at an affordable price point. Leveraging our extensive expertise, we’ve engineered the perfect everyday sleeve for you. The result is a durable sleeve with an exceptional shuffle-feel.

Rest assured, these sleeves won’t strain your budget, yet they’re built to withstand numerous games without faltering. We’ve spared no effort in ensuring a precise fit, premium materials, and meticulous production standards.

Furthermore, you have the flexibility to choose between standard and Japanese sizes, depending on the TCG you play.
