Boulder-Tough Protection for Your Most Important 100
The Ultimate Guard Boulder Deck Case 100+ XL is built like its name implies — a rigid, impact-resistant shell that takes the knocks of your bag so your deck doesn't have to. The Witherbloom edition brings the swampy, organic aesthetic of the Strixhaven college to the exterior, making this more than a protective case: it's a statement about how you play. The Boulder line is one of Ultimate Guard's most trusted formats, and for good reason — the polypropylene construction feels genuinely solid in hand, not hollow or brittle like cheaper alternatives.
Capacity & Sleeve Compatibility
The 100+ XL designation means this box is sized for Commander. It comfortably fits 100 cards in standard sleeves, and the XL build accommodates double-sleeved decks — a premium feature that competitive and Commander players will appreciate. If you're running inner sleeves beneath your Dragon Shields or KMC Hyper Mattes, this box handles the added bulk without forcing the lid or warping the shell over time.
Closure & Access
The Boulder uses a secure snap closure that opens cleanly and holds firmly when shut. The lid stays open during play, so you're not fighting it when pulling your deck mid-game. A thumb notch at the front of the box makes drawing out your sleeved deck clean and effortless — no awkward digging. The interior is smooth, keeping sleeves from catching or scuffing on the way in and out.
Who This Box Is For
The Boulder 100+ XL Witherbloom is built for the Commander player who takes their deck seriously. Whether you've invested in premium sleeves, foiled out your list, or just want the peace of mind that comes from genuinely tough protection, this is the daily carry that delivers. The Witherbloom art direction — earthy tones, botanical detail, that signature Strixhaven college energy — makes it a natural fit for anyone piloting a Witherbloom precon or a custom life-gain build. It also makes a strong gift for the Magic player in your life who has strong college allegiances.
