Ultimate Guard Bundle: Onyx

If you can’t decide on a colour, Onyx is the answer Ultimate Guard’s darkest Boulder deck box paired with 100 matching Black Cortex sleeves. It hides fingerprints and shuffle-wear better than any bright colourway, and it goes with literally any deck, any playmat, any table. The safe pick that never looks like a compromise.

What’s in the box

• Ultimate Guard Boulder 100+ deck box, Clear Onyx, soft-touch finish
• 100x Cortex sleeves, standard size (66 x 91mm), Black
• Case holds 100 double-sleeved cards, or up to 120 single-sleeved

Why it’s good

• Glossy black Cortex sleeves keep card backs fully opaque at the table
• Soft-touch Boulder case is durable enough for weekly shop nights

Whatever you’re playing Magic, Pokmon, Lorcana, One Piece black sleeves and a black box never clash with it.

One box, 100 sleeves, zero decisions to make. See every other colourway in our Ultimate Guard collection, or browse deck boxes on their own.
