Amethyst isn't a colour you get in every card shop, and the Boulder 100+ wears it well. This rigid, soft-touch case from Ultimate Guard is built to keep a double-sleeved deck safe in transit — no bent corners, no card ends poking free, just a solid shell that clicks shut and stays shut.
Best for
Standard-size decks up to 100 cards double-sleeved (120 single-sleeved, 210 bare)
Players who want a proper snap-shut case rather than a flimsy box
Slotting into bigger Ultimate Guard mass storage — the Arkhive, Superhive and Flip'n'Tray ranges
Pop the lid and it opens smooth and easy one-handed; snap it shut and your deck isn't going anywhere until you want it to.
A dependable case built to travel. Browse our full range of card sleeves to get your deck double-sleeved and ready to go in, or see the rest of the deck box range for other sizes and colours.

How many cards does it hold — and does that count sleeves?
Capacity figures on deck boxes are for sleeved cards, so a box rated 100+ holds a 100-card deck in standard sleeves, with the plus giving headroom for a few tokens or extras. If you double-sleeve, treat the rated number as optimistic and size up.
Will a Commander deck fit?
A 100+ box takes a Commander deck in single sleeves with a bit of room for the commander and a handful of tokens. Double-sleeving, or carrying a full token and dice setup, wants a 133+ or larger — the extra couple of pounds saves the daily annoyance of a lid that won't quite shut.
Is it worth paying more for a premium deck box?
For a deck you carry around, usually. The differences that actually matter are a lid that stays shut in a bag, a shell rigid enough to survive being sat on, and a lining that won't scuff your sleeves. A cheap box is perfectly fine sitting on a shelf — it's transport that finds its limits.
Can I store a deck in here long term?
Yes, as long as the cards are sleeved and the box lives somewhere dry and out of direct sunlight — light and humidity do far more damage than any box. If you're storing a collection rather than a deck, a portfolio is easier to browse and kinder to the cards.
