Sidewinder has earned its reputation as one of the most reliable rigid deck cases in the hobby, and this updated version takes the formula further with a capacity that finally matches how competitive and Commander players actually build their decks. If you double-sleeve your cards, this box was designed around you.\u003c\/p\u003e\u003ch2\u003eCapacity \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sidewinder 133 holds up to \u003cstrong\u003e133 double-sleeved standard-size cards\u003c\/strong\u003e or \u003cstrong\u003e160 single-sleeved cards\u003c\/strong\u003e in Ultimate Guard sleeves. That double-sleeve figure is the headline — it puts this box in rare company for players running inner sleeves under their outers. Standard Magic: The Gathering, Pokémon TCG, and similarly sized card games all fit comfortably. The box dimensions are \u003cstrong\u003e104 × 111 × 78 mm\u003c\/strong\u003e, giving you a compact but genuinely roomy shell without bulk you don't need.\u003c\/p\u003e\u003ch2\u003eBuild \u0026amp; Closure\u003c\/h2\u003e\u003cp\u003eThe Sidewinder name comes from the side-loading design — cards slide in horizontally, which reduces stress on sleeves during daily access. Ultimate Guard builds this box from their signature rigid polypropylene shell with a \u003cstrong\u003emagnetic closure\u003c\/strong\u003e that snaps shut with satisfying firmness. The lid stays where you put it, whether that's open during a game or closed in your bag. The thumb notch is well-positioned for quick single-hand access — a small detail that adds up across hundreds of game nights.\u003c\/p\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Sidewinder 133 is the go-to for players who take card protection seriously. If you double-sleeve — whether for preservation, tournament longevity, or both — this is the box that earns a permanent spot in your bag. It's equally strong as a Commander box for a well-loved 100-card build or a competitive Modern and Pioneer player's tournament carry. Ultimate Guard gear is built to last, and this box reflects that commitment to long-term quality over throwaway convenience.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eUltimate Guard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity (Double-Sleeved)\u003c\/td\u003e\n\u003ctd\u003e133 cards\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity (Single-Sleeved)\u003c\/td\u003e\n\u003ctd\u003e160 cards\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCard Size\u003c\/td\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBox Dimensions\u003c\/td\u003e\n\u003ctd\u003e104 × 111 × 78 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClosure\u003c\/td\u003e\n\u003ctd\u003eMagnetic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eRigid polypropylene\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDouble-Sleeve Compatible\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExtras\u003c\/td\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Boreal Gaming \u0026 Cards","offers":[{"title":"Default Title","offer_id":44481057882200,"sku":"33037921","price":44.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/4980\/8728\/files\/UGDDC011615.jpg?v=1785422544","url":"https:\/\/borealgaming.com\/products\/ultimate-guard-sidewinder-133-standard-size-deck-case","provider":"Boreal Gaming \u0026 Cards","version":"1.0","type":"link"}
