Ultimate Guard Boulder Deck Case 100+ Solid Black

Built Like Its Name, Trusted Like a Vault

The Ultimate Guard Boulder 100+ in Solid Black is the no-nonsense daily carry that serious players reach for when they want their deck protected without compromise. The Boulder line earns its reputation through a rigid polypropylene shell that resists crushing, a satisfying magnetic closure that snaps shut with authority, and a clean matte finish that holds up session after session. This is the solid black colourway — understated, tournament-appropriate, and built to last.

Capacity & Compatibility

The Boulder 100+ is designed to hold up to 100 double-sleeved cards — meaning your Commander deck with inner sleeves and outer sleeves fits without forcing. Single-sleeved standard decks have room to breathe. The wider body accommodates the extra bulk that double-sleeving adds, making this a genuine 100+ solution rather than a nominal one. If double-sleeve compatibility is your primary filter, the Boulder 100+ earns that checkmark.

Build & Closure

The magnetic closure delivers a firm, positive shut every time — no rattle, no accidental opening in a bag. The hinged lid is designed to stay open during deckbuilding and play, so you're not wrestling with a lid while pulling cards mid-game. A thumb notch on the front of the box makes drawing out your deck clean and effortless. The exterior shell is polypropylene — impact-resistant and lightweight — and the interior lining protects card sleeves from scuffing against hard plastic edges.

Who It's For

The Boulder 100+ Solid Black is the go-to for Commander players who want one reliable box for their flagship deck and don't need to broadcast their brand loyalties. It's equally at home at FNM, a weekend tournament, or a kitchen table league night. If you're buying a deck box for someone who takes their cards seriously, this is the kind of gift that gets used every single week.
