Shell Up. Your Deck Deserves It.
The Ultimate Guard Squaroes 100 Boulder brings serious deck protection wrapped in a design that Turtle fans will immediately recognize. Built as the next generation of the beloved Boulder line, the Squaroes trades the rounded silhouette for a bold square-edged form factor — and the result is a deck box that feels as sturdy and dependable as the heroes it's modelled after. The shell is notably rigid, engineered to take the bumps of a tournament bag or backpack without flexing or cracking, and the airtight seal keeps moisture and dust away from your cards between sessions.
Built for 100 — Sleeved and Ready
The Squaroes 100 holds up to 100 single-sleeved cards, making it the right size for a full Commander, Lorcana, Riftbound, or One Piece deck straight out of the box. Double-sleeve compatibility is not confirmed for this model — players running inner sleeves plus outers should verify fit before committing. The square profile also stacks cleanly, which is a practical bonus for players managing multiple decks on a shelf or in a bag.
Closure & Construction
The Boulder line has always been defined by its signature closure — a satisfying snap that holds firm without needing a latch or strap. The Squaroes continues that tradition. The shell material is Ultimate Guard's own proprietary polypropylene construction, giving it the rigid feel and impact resistance the Boulder series is known for. Opening is comfortable and accessible, with the lid designed to release cleanly even mid-session without fumbling. The airtight seal is a step up from standard snap-lid boxes, adding a layer of protection that matters if you're carrying your deck through unpredictable weather or a packed convention floor.
Cowabunga-Approved Collab Design
This isn't a generic licensed slap-print — the Teenage Mutant Ninja Turtles edition is a proper collaboration product in the Squaroes lineup, sitting alongside other pop-culture and TCG-branded releases. Whether you're a longtime TMNT fan, a collector who loves a themed build, or just want your deck box to stand out on the table, this release delivers a distinct visual identity that no plain black box can match.
Who This Is For
The Squaroes 100 Boulder TMNT edition is a natural fit for Commander players, One Piece and Lorcana collectors, and anyone who wants the quality of Ultimate Guard's proven Boulder platform with a design that reflects their personality. It also makes a genuinely excellent gift for the TCG player in your life who is also a Turtles fan — a combination more common than you might expect at any local game store.
