Product questions

How many cards does this Boulder hold?

Ultimate Guard lists this deck box at 100 double-sleeved cards, 120 single-sleeved cards, or 210 unsleeved cards. Capacity is based on standard-size cards and Ultimate Guard sleeves.

What makes the Hybrid version different?

The Hybrid version combines a transparent top section with a soft-touch base. That gives you a clearer view of the deck inside while keeping the familiar Boulder feel and secure closure.

Will it fit any sleeved deck exactly the same way?

Not always. Ultimate Guard states the box is designed for Ultimate Guard sleeves, and sleeves from other brands may affect overall capacity and fit.

Give your blue-aligned deck a clean, durable home with the Ultimate Guard Boulder 100+ Hybrid Island edition from Monmouth Cards.
