Mahjong, made the way it should be.

Our story

We started Bone & Bam because every mahjong set on the market was either a four-figure antique or cheap, ugly plastic — and nothing in between. So we made the set that should have existed.

The studio sits under the Front Range in Denver. Tiles are poured from three layers of recycled PMMA — an antique ivory face, a six-millimeter colored edge that names the colorway, and a tonal base that anchors the weight.

We make small batches. We answer our own emails. We don't believe in seasonal urgency — only in making things you'll still want to bring out twenty years from now.

Three things we will not compromise.

Recycled

PMMA, three layers.

Every tile is poured from recycled acrylic — face, edge, base — bonded into a single nineteen-millimeter object.

Engraved

CNC, then by hand.

Designs are CNC-engraved at 0.3mm to reveal the colored layer below. No paint, no print, no shortcuts.

Colorado

Made in Denver.

Designed, finished, and packed in a small studio under the Front Range. Small batches, only as many as we can do well.
