These Colored-Back Card Sleeves are designed 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 card sleeve manufacturers state their MTG sleeves as this much bigger size, for no reason we can figure out other than that their sleeves are way too big. These fit GREAT, so don't let the stated dimensions fool you!

This is the all-new MDG-7141 Card Sleeve by Mayday Games. It comes with 80/pack and features a thick color-backed card sleeve that is slightly textured and of a matte finish. They are perfectly clear and have no annoying circular logo in the corner to cover up text. They also come in packs of 80, what most players say they prefer.

Card Sleeves FAQ

What is the purpose of card sleeves? 
Card sleeves protect your cards from damage and wear.

What's the difference between Premium and Standard card sleeves? 
Premium card sleeves are 125% thicker than Standard card sleeves, making them more durable than Standard sleeves. Cards sleeved in Premium Card Sleeves feel really nice, crisp and substantial. 

If space in your game box is tight, however, Standard Card Sleeves might be a better choice as Premium-sleeved cards will noticeably take up more room.

Premium Card Sleeves typically come in packs of 50, while Standard Card Sleeves usually come in packs of 100. You'll want to take this into consideration when calculating the number of packs you need to order.

Will card sleeves scratch my cards? 
No, card sleeves are specifically designed to prevent scratches and other damage to your cards.

How do you properly sleeve cards? 
Slide your card into the sleeve, bottom first.

If you are double sleeving, slide your card into the first/inner sleeve, top first. The sleeve opening will be at the bottom of the card.
Then slide your sleeved card into the outer sleeve top first, effectively sealing it in. The outer sleeve opening should be at the top.

What is Double Sleeving? 
Double Sleeving provides extra protection to your cards. Double Sleeving helps keep your cards dust-free and provides some protection from water.

How do you flatten sleeves on cards? 
Usually, card sleeves flatten over time and use. Some people use binders to flatten them faster.
