Questions

What are perfect size sleeves used for?
They are inner sleeves that fit snugly around standard cards, then slide inside regular outer sleeves for double-sleeve protection. The black back prevents your cards from being marked when using semi-opaque outer sleeves.

Will these fit inside standard outer sleeves?
Yes. At 89mm x 64mm, they are sized to fit standard cards and then fit inside KMC standard sleeves, Dragon Shield sleeves, and other standard outer sleeves.

Why use black-backed inner sleeves instead of clear?
The black back provides an opaque layer behind your card, preventing marked cards when you use translucent or semi-opaque outer sleeves in tournaments.
