Katana Sleeves: Premium Card Sleeves by Ultimate Guard 

Ultimate Guard Katana Sleeves are the epitome of quality when it comes to protective sleeves for trading card games. As the result of years of research and material optimization, Katana Sleeves are significantly more durable and tear-resistant than standard sleeves, reliably protecting your cards from dirt, wear, and mechanical damage.
The specially textured back also makes Katana Sleeves the ultimate choice for an exceptionally smooth shuffle feel — a detail especially appreciated by tournament and casual players alike. The ultra-clear front lets even the most stunning foil cards shine in full glory, while the opaque, sturdy material on the back meets the highest demands of tournament play.
Whether Magic: The Gathering, Pokémon, Riftbound, Lorcana, Yu-Gi-Oh!, or other TCGs: Katana Sleeves are the premium choice for virtually every trading card game and are beloved and valued by players and collectors worldwide.

Frequently Asked Questions about Katana Sleeves

The material of Katana Sleeves is extremely durable and tear-resistant — even though Katana Sleeves are thinner than many comparable products from other brands. The textured back provides a perfect shuffle feel and offers high opacity for perfect sight-shielding, which is especially important for tournament players and when using double-sided cards. The front is also ultra-clear, letting your cards look their absolute best. Katana Sleeves are acid free and PVC free.

Katana Sleeves are available in two sizes. Standard Size measures 66 × 91 mm and fits all common standard-size TCGs such as Magic: The Gathering, Pokémon, Riftbound, Lorcana, One Piece, or Flesh and Blood. Japanese Size is slightly smaller at 62 × 89 mm and was designed for card games such as Yu-Gi-Oh! or Cardfight!! Vanguard. As a rule of thumb: cards in the standard size of 63 × 88 mm fit Standard Size sleeves, while cards measuring 59 × 86 mm belong in Japanese Size sleeves.

Katana Sleeves are the premium sleeves in Ultimate Guard's lineup and represent the highest possible quality. Cortex Sleeves are the more affordable alternative for everyday use, offering a very high standard as well, though slightly below Katana quality in terms of material, durability, and shuffle feel. Both sleeves also differ in the structure of the back. One advantage of Cortex Sleeves: they're also available in a matte, non-reflective front version.

The color range of Katana Sleeves in Standard Size currently includes 19 colors: Transparent, Orange, Yellow, Turquoise, Black, White, Green, Red, Blue, Blue Bird, Jade Garden, Iris Bloom, Great Wave, Rising Sun, Mountain Haze, Radiant Plum, Autumn Moon, Summer Cloud, and Obsidian Shard. Katana Sleeves in Japanese Size are currently available in Black, Blue, Red, Turquoise, and White. Developing new colors and variants is a constant priority for Ultimate Guard, so our range will keep expanding accordingly.

Yes. Katana Sleeves are even known as one of the leading tournament sleeves for TCGs and are valued by casual players and pros worldwide for exactly that reason. What sets them apart is their high opacity and material quality: they prevent the sleeves from developing damage marks even under intensive use — marks that could otherwise be considered "marked cards," which in the worst case can lead to disqualification.

Katana Sleeves are naturally compatible with all Ultimate Guard products, such as inner sleeves, deck boxes, and binders. Thanks to their comparatively thinner profile, they're also generally compatible with storage products from other manufacturers. However, we strongly recommend comparing the dimensions of all products beforehand.

Yes, Katana Sleeves are very well suited for double-sleeving. We recommend using Ultimate Guard inner sleeves for this purpose: both our Precise-Fit Sleeves and the Katana Inner Sleeves designed specifically for this use fit perfectly inside Katana Sleeves.

Due to their huge popularity among players and collectors, as well as the elaborate manufacturing process required to maintain quality, Katana Sleeves sometimes sell out quickly. Ultimate Guard is continuously working to expand production capacity in order to meet high demand on an ongoing basis.
