Built Like Its Name Suggests
The Ultimate Guard Boulder Deck Case 100+ in Solid Green is a no-nonsense, tank-built card case designed for players who want maximum protection without the bulk of a full-featured box. The Boulder's defining characteristic is its rigid polypropylene shell — rounded, smooth, and engineered to absorb the knocks and drops that come with regular transport to game nights, tournaments, and local store events. This is a deck box that earns its name through material honesty rather than marketing language.
Capacity & Sleeve Compatibility
The Boulder 100+ is built to hold 100 double-sleeved cards or up to 120 single-sleeved cards, making it one of the more generous options in its form factor. That double-sleeve compatibility is a genuine selling point — players running a full Commander or competitive 60-card deck in inner sleeves plus outer sleeves will find the fit snug but functional. The slightly oversized 100+ designation means you're not wrestling the lid shut over a freshly double-sleeved deck.
Build Quality & Closure
The Boulder closes with Ultimate Guard's secure snap closure — no magnet, no strap, just a clean, positive-click lid that stays shut in a bag without any fuss. The rigid outer shell doesn't flex under pressure, which matters when it's sitting at the bottom of a backpack. The interior is smooth and card-access is straightforward, with a thumb notch that lets you get into the deck quickly without pawing at the top card. The lid opens fully and stays open during play so it won't interfere at the table.
Who It's For
The Boulder 100+ is the go-to choice for the competitive or semi-competitive player who wants a single, reliable case that handles double-sleeved decks without drama. It's equally at home as a Commander deck box or as everyday carry for a Modern or Pioneer build. The Solid Green colourway is clean and low-profile — easy to spot in a bag, easy to match with green-sleeved builds, and understated enough to work at any table. If you're looking for a straightforward gift for a player who takes their deck seriously, this is a safe and well-regarded choice.
