Kiiransr MTG Card Sleeves – Underground Sea (Blue Black) – 100 Standard Size Sleeves with Clear Front and Matte Back

The Kiiransr MTG card sleeves in the Underground Sea (Blue Black) design pack 100 standard-size sleeves (66mm x 92mm) for Magic: The Gathering and other trading card games. The clear front shows off your cards while the matte back cuts down glare and fingerprints, and the polypropylene material is acid-free and PVC-free for long-term storage.

What makes these sleeves different?

The Underground Sea artwork comes from the Fantasy Dual Lands series, giving your deck a distinctive blue-black Dimir look. The matte finish on the back isn't just about looks – it makes shuffling smoother and keeps your sleeves from sticking together. Since the front stays ultra clear, your foil cards and rare arts stay visible without distracting reflections.

Each sleeve is tear-resistant and dustproof, designed to protect against scratches and bends during play or transport. The 100-count pack gives you enough for a full commander deck with a few extras.

Technical specifications

Will these sleeves fit my cards?

Yes, they fit all standard-size trading cards – that includes Magic: The Gathering, Pokémon, Yu-Gi-Oh!, and similar TCGs. The 66mm x 92mm interior matches the standard card size exactly, so your cards slide in snugly without being too tight. The clear front is designed to stay transparent over time, and the matte back won't become cloudy or sticky with normal use.

How does the matte finish help during play?

Matte sleeves reduce glare from overhead lights, which can be a real problem at tournaments or bright game stores. They also resist fingerprints, so your sleeves stay clean longer. The texture adds grip for easier shuffling, and the non-reflective back keeps your opponent from seeing card edges or marks that could give away information.

Common questions about these sleeves

Are they suitable for double-sleeving?

The supplied information does not specify compatibility with inner sleeves. These sleeves are standard-sized, so they may work with some inner sleeves, but it's best to test a single card before committing to a full deck.

Can I use them for cards other than MTG?

Yes, they fit any standard-size TCG card (like Pokémon or Yu-Gi-Oh!), as long as the card dimensions match the 66mm x 92mm standard.

How many decks can I sleeve with one pack?

A 100-count pack covers one 100-card commander deck with a few leftover sleeves, or about one and a half 60-card decks (60 + 60 = 120, so you'd need two packs for two 60-card decks).

What makes the Underground Sea design special?

The artwork is part of the Fantasy Dual Lands series, capturing the original MTG dual land art style in a blue-black Undeground Sea theme. It's a nod to the classic card many players know from the early days of Magic.
