Can't get this one right now?
Hand over the choice instead. A Loaded Dice eGift Card arrives by email in seconds and spends on anything we stock — so they can grab this the moment it's back, or pick something else entirely.
Standard size sleeves fit the 63 x 88mm cards used by Magic: The Gathering, English-print Pokémon, Disney Lorcana, One Piece, Star Wars Unlimited and most Western trading card games. If you play Yu-Gi-Oh, or collect Japanese-print Pokémon, those cards are smaller and need Japanese size instead.
A 100-count pack covers a 60-card Magic or Pokémon deck with plenty spare to replace any that split. A 100-card Commander deck needs two packs — sleeve exactly 100 and you'll have nothing left the first time one splits, which it will.
Can I double-sleeve with these?
Yes. Double-sleeving means a thin perfect-fit inner sleeve on the card first, then these as the outer — it seals the card in and stops dirt working its way past the opening. It's the standard approach for a deck you're taking to events, though it does bulk the deck out, so check your deck box has the headroom.
Matte or gloss — does it actually matter?
Mostly preference, but the differences are real. Matte shuffles better, kills glare under bright hall lighting and photographs far better; gloss slides faster and keeps artwork looking sharper. Competitive players tend towards matte, and it's worth sleeving a whole deck in one finish — a mixed deck can effectively mark your own cards.
