Gristle Glutton Sidewinder 100 Deck Box

Built for Double-Sleeved Decks, Decorated for the Table

The Ultimate Guard Sidewinder 100 in the Gristle Glutton design isn't just a box — it's a daily carry that earns its place in your bag. Constructed in Ultimate Guard's Xenoskin material, the Sidewinder delivers a premium matte finish that resists scuffs, feels substantial in the hand, and looks sharp whether you're pulling it out at your local game store or across the table at a tournament. The full-colour Gristle Glutton artwork wraps the shell with the kind of detail that makes your setup feel intentional, not generic.

Capacity and Sleeve Compatibility

The Sidewinder 100+ is engineered to hold 100 double-sleeved cards in Ultimate Guard sleeves, making it a strong choice for Commander players and anyone who runs inner sleeves for extra protection. It also fits up to 120 single-sleeved cards, covering standard 60-card and 75-card competitive builds with room to spare. Double-sleeve compatibility isn't an afterthought here — it's the designed-for use case, and the interior dimensions reflect that with a snug, rattle-free fit.

Sidewinder Closure and Access

The Sidewinder design opens from the side rather than the top, which means your cards stand upright and you can flip the lid without disturbing the deck. The closure uses Ultimate Guard's signature magnetic system — firm, positive, and reliable after hundreds of open-and-close cycles. The lid stays open during play without creeping shut, and a smooth thumb notch makes one-handed access natural and quick. Xenoskin's semi-rigid shell protects the contents from light impacts and everyday bag wear.

Who This Is For

This box is aimed at the player who double-sleeves their cards and wants a deck box that keeps pace with that investment. If you run a Commander deck with expensive staples, sleeve everything twice, and want a box that reflects the care you put into the build, the Gristle Glutton Sidewinder delivers on all of it. It also makes a strong gift for the MTG or TCG player in your life who takes their collection seriously — the artwork gives it personality, and the Xenoskin build gives it longevity.
