Mayday Games Standard Card Sleeves (80) - 66 x 91 mm - Black Backed
These are for cards that are 63.5 X 88 MM, like Magic The Gathering Cards. So why are they stated as having dimensions of 66 X 91 MM? Good question. Some of our main competitors state their MTG sleeves as this much bigger size, for no reason we can figure out other than that their sleeves are way to big. These fit GREAT, so don't let the stated dimensions fool you!
