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.
