Built Like a Boulder, Themed Like a Forest
The Ultimate Guard Boulder Deck Case has earned its reputation as one of the most reliable rigid deck boxes in the hobby — and the Mana Edition Forest variant earns its place in that lineage by wrapping that same tank-like construction in artwork inspired by Magic: The Gathering's iconic Forest mana symbol. This isn't a cosmetic novelty slapped onto a generic shell. The Boulder's thick polypropylene construction, smooth hinge, and signature self-locking lid make it a genuine daily-carry option for players who want their deck protected and their aesthetic on point.
Capacity & Sleeve Compatibility
The Boulder 100+ is built for Commander and other 100-card formats. It comfortably fits 100 single-sleeved cards, and the 100+ designation means there's genuine breathing room for double-sleeved decks as well — a meaningful detail for players who run inner sleeves under their Dragon Shields or KMCs. Deck, tokens, and a few extra sleeves can coexist without forcing the lid. If you're playing a 60-card format, you'll have room to spare.
Build Quality & Closure
The Boulder's defining feature is its self-locking lid mechanism — no magnets, no external strap, just a satisfying click that holds the lid securely closed during transport. The rigid polypropylene shell resists flex and crush better than softer deck boxes, making it a favourite for players who toss their gear into a backpack without a second thought. The lid stays open flat during play, keeping your deck accessible without the box tipping over — a small detail that tournament players notice immediately.
Mana Edition Forest Design
The Mana Edition series pays direct tribute to Magic: The Gathering's five colours of mana. The Forest edition draws on the green mana identity — expect deep woodland tones and the imagery players have associated with Forests since Alpha. It's a clean way to colour-code your decks by mana identity, or simply to carry a box that reflects your favourite playstyle. The artwork is integrated into the moulding and print, not a sticker or sleeve that will peel over time.
Who This Is For
The Boulder 100+ Mana Edition Forest is the right pick for the Commander player who wants dependable protection with a Magic-native aesthetic. It also works as a thoughtful gift for the green-mana devotee in your playgroup — someone who runs Elves, Forests, or just loves the flavour of Gaea's domain. Ultimate Guard builds these to last, and the Boulder line has been a staple at Boreal Gaming for players who don't want to second-guess their gear.
