Built Like Its Name — The Boulder Holds Its Ground
The Ultimate Guard Boulder 100+ in Eclipsed Boggarts isn't trying to impress you with bells and whistles — it earns its reputation through sheer build quality. Constructed from rigid polypropylene, the Boulder has a reassuring heft and solidity that separates it immediately from flimsy snap-lid cases. This is a deck box that survives the bottom of a backpack, survives tournament tables, and survives the kind of everyday carry that weeds out lesser products fast.
Capacity & Sleeve Compatibility
The 100+ designation means business: the Boulder holds up to 100 double-sleeved cards — fully compatible with standard double-sleeving setups — or up to 120 single-sleeved cards in Ultimate Guard sleeves. That Commander deck with a full set of inner sleeves and outer sleeves? It fits. The generous capacity makes this a go-to choice for 100-card formats without forcing you to squeeze or compress your deck to close the lid.
Closure & Access
The Boulder uses a secure snap closure that stays firmly shut during transport without requiring a magnet or strap. The lid opens wide and stays stable during play, and the thumb notch cutout gives clean, easy access to your deck without fumbling. The interior is smooth and sized to let cards slide in and out without resistance — a small detail that matters every single time you sleeve up before a game.
Eclipsed Boggarts
The Eclipsed Boggarts colourway brings a dark, textured aesthetic to the Boulder line — a design that reads as understated and confident on the table. If your deck has a personality, your deck box should too, and the Boggarts finish delivers without leaning into anything garish. It's the kind of colour choice that ages well.
Who Should Pick This Up
The Boulder 100+ is the deck box for players who want reliability above everything else. Commander players running double-sleeved 100-card decks will find it sized exactly right. Tournament regulars who need a box that survives constant travel without cracking or warping will appreciate the rigid construction. It's also a strong gifting option for any player — hard to go wrong with an Ultimate Guard Boulder at any level of play.
