Specifications

How does the secure closure work?

The Boulder uses a dual-action snap mechanism: the lid clicks into place with a firm resistance, and the hinge is overbuilt to avoid cracking after repeated use. The lock stays shut even when the case is shaken or dropped, so your cards won’t spill out during transit. The lid also has a slight overhang that keeps dust and moisture away from the opening.

What does the soft-touch surface allow?

The outer shell is a translucent plastic coated with a fogged, soft-touch film. This creates a non-slip grip that keeps the case from sliding off a table or out of your hand. More notably, the slight translucency lets you see which deck is inside—even if the case is closed—without fully opening it. This is useful when you have multiple Boulders stacked and need to grab the right one quickly.

Can the Boulder combine with other Ultimate Guard products?

Yes. The Boulder 100+ is part of Ultimate Guard’s modular system. It fits inside the Arkhive (holds up to 4 Boulders), Treasurehive (holds up to 6), and other Hive-family cases. You can also stack Boulders on their own—they interlock via subtle grooves on the bottom and top, so they won’t slide apart in a bag. This lets you build a custom storage setup that matches your collection size.

Frequently asked questions

Does the Malachite color show fingerprints?

The soft-touch coating reduces visible fingerprints and smudges. The Malachite pattern—a green marbled effect—also helps mask minor marks. Regular cleaning with a damp cloth keeps it looking fresh.

Can I use this case for unsleeved cards?

Yes, but the interior is intended for sleeved cards. Unsleeved cards may shift slightly, and the case will hold more than 120 unsleeved cards—though that’s not the recommended use. For best protection, use sleeves.

Is the case waterproof?

The plastic shell and snug closure provide a good seal against splashes and minor spills, but the case is not submersible. Avoid leaving it in heavy rain or exposing it to prolonged moisture.
